With regard to GH1-Myb4 and GH1-Myb5, which also are described as TRB proteins in many databases, we suggest removing the designation TRB from their names. matching the last 14 amino acids that are different in this variant). official website and that any information you provide is encrypted ), the Foundation for Polish Science (TEAM to K.G.) Maximum-likelihood phylogenetic tree and domain architecture of Arabidopsis GH1-containing proteins. We have argued previously that the formal criteria that define a typical linker histone (i.e. S1). In 1926, James B. Sumner, showed that urease is a protein by examining its crystallized form. Interestingly, all three proteins lacking Myb are encoded by neighboring genes on chromosome 1. Sequences of all GH1-containing proteins used for phylogenetic comparison were screened with SMART (Schultz et al., 2000; Letunic et al., 2015) for the presence of any additional domains or loss of domains (other than GH1). Careers. According to secondary structure predictions, the two other proteins lacking the Myb domain (AT1G54230 and AT1G54240) have -helical regions within their CTDs. The expression of eukaryotic genes is controlled primarily at the level of initiation of transcription, although in some cases transcription may be attenuated and regulated at subsequent steps. sharing sensitive information, make sure youre on a federal performed proteomic analyses; K.R. GH1 consists of 80 amino acids and belongs to the winged helix family of DNA-binding proteins. The tree image was prepared with iTol (Letunic and Bork, 2011). It is important to remember that proteins of these two types from other species still retain their AT-hook motifs and Myb domains. In addition to GH1, the overall functional properties of H1 are strongly influenced by the CTD, which binds to internucleosomal linker DNA. This suggests that AT1G48610, which we believe to be a true Arabidopsis HMGA protein, is important in the differentiation of stem cells, a role highly reminiscent of that played by animal HMGA-type proteins (Ozturk et al., 2014). The fusion of genuine GH1 and multiple AT-hook motifs that occurred in angiosperm plants also can be found in phylogenetic groups outside the plant kingdom, such as in numerous fish species, in Trichoplax adhaerens, the only extant representative of the phylum Placozoa (a primitive group of multicellular animals), as well as in some yeast, nematode, and insect species. For example, as illustrated in Table I and Supplemental Table S1, plant linker histones, like high-mobility group A (HMGA) and certain other proteins, are described by the general term winged helix DNA-binding transcription factor in several databases. In Medicago truncatula, a GH1-Myb protein has an additional RNA-recognition motif. H1s, also known as linker histones, are universal and ubiquitous components of chromatin fibers, in which they occur at an average frequency of one molecule per nucleosome (Woodcock et al., 2006). Search by keyword(s) and/or select/deselect filters. The fish and T. adhaerens genomes encode very large proteins (up to 2,900 amino acids) in which GH1 and AT-hook motifs cooccur with RING and PHD domains. In the Arabidopsis GH1 evolutionary tree, both of these proteins group in a clade separate from that of TRB1 to TRB3, suggesting a greater evolutionary distance. Moreover, and probably due to its high pI, it was copurified during the isolation of Arabidopsis linker histones by extraction with 4.5% PCA (perchloric acid) and cation-exchange chromatography (Kotliski et al., 2016). This system will be useful as a basic reference tool for the identification and characterization of homologous proteins from different plant species. Cells can acquire specified function and carry out various The net charge was summed in a 20-amino acid sliding window along N- and C-terminal regions, starting from the GH1 domain. AT1G54260.1 also contains a strongly diverged and truncated GH1 domain at the C-terminal side of its regular GH1 domain. The nucleosome is the fundamental subunit of chromatin.Each nucleosome is composed of a little less than two turns of DNA wrapped around a set of eight Protein sequences for model plants were collected via phmmer (Finn et al., 2011), available from the Ensembl Plants Web site (Kersey et al., 2014). This gene encodes the pro-alpha1 chains of type I collagen whose triple helix comprises two alpha1 chains and one alpha2 chain. Previously, we demonstrated that this branch separated from the main H1 variants roughly 140 million years ago, which coincided with the appearance of angiosperm plants on Earth (Rutowicz et al., 2015). This concept is by no means equivalent to suggesting that all plant GH1-containing proteins are bona fide H1 variants, in a sense ascribed to this subcategory in animal studies. Papillomaviridae is a family of non-enveloped DNA viruses whose members are known as papillomaviruses. As a result, these three properties affect the way they interact with their surroundings within polypeptides and proteins. Editor/authors are masked to the peer review process and editorial decision-making of their own work and are not able to access this work in For better taxon sampling, the following representatives of missing major taxon groups were added: Auxenochlorella protothecoides, Coccomyxa subellipsoidea, Marchantia polymorpha, Picea sitchensis, Pinus taeda (from UniProt), and Klebsormidium flaccidum (from NCBI genomes). All three were detected in our analysis of the nuclear proteome of an Arabidopsis T87 cell suspension culture (Supplemental Table S1; http://proteome.arabidopsis.pl). Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Two other GH1-Myb proteins, GH1-Myb4 and GH1-Myb5 (AT1G17520.1 and AT1G72740.1, respectively), are more distantly related to GH1-Myb-TRB1 to GH1-Myb-TRB3 (Supplemental Fig. Interestingly, the At1g48610 locus in chromosome 1 is located next to that encoding the H1-HMGA2 protein. Since the GH1-Myb-TRB1 and GH1-Myb-TRB2 proteins have been experimentally confirmed to bind telomere repeats and, therefore, were named TRB1 and TRB2, we propose to retain this functional reference in their names (as GH1-Myb-TRB) for the sake of clarity and tradition. Laboratory of Systems Biology, Faculty of Biology, University of Warsaw, 02-106 Warsaw, Poland (M.K., A.J. The same applies to GH1-Myb-TRB3, a very similar protein that has been described previously as TRB3. The protein encoded by this gene is a member of the fibroblast growth factor receptor family, where amino acid sequence is highly conserved between members and throughout evolution. (2014), Ensembl Genomes 2013: scaling up access to genome-wide data, Kotliski M, Rutowicz K, Kniewski , Palusiski A, Oldzki J, Fogtman A, Rubel T, Koblowska M, Dadlez M, Ginalski K, et al. 54 have been classified as cancer-associated proteins. The split into typical H1s and GH1-HMGA/GH1-HMGA-related preceded the separation of the GH1-Myb/GH1-Myb-related subgroup. Type I is a fibril-forming collagen found in most connective tissues and is abundant in bone, cornea, dermis and tendon. width: 77%; conceived the project; M.K., C.B., and A.J. S3; Schmidt et al., 2011). GH1 associates with the nucleosome outside the core particle and contacts DNA via at least two different binding sites (Zhou et al., 1998, 2013; Brown et al., 2006; Syed et al., 2010). AJOG's Editors have active research programs and, on occasion, publish work in the Journal. float:right; Moreover, it was shown by genome-wide expression (RNA sequencing) analysis that TRB1, by binding at these loci, plays the role of transcriptional regulator, which is independent of its role in telomere maintenance (Zhou et al., 2016). Chromatin Structure and Dynamics: State-of-the-Art. 2011/02/A/NZ2/00014 and 2014/15/B/NZ1/03357 to K.G. Based on published data and our in silico and high-throughput analyses, we propose a systematization and coherent nomenclature of GH1-containing proteins of Arabidopsis (Arabidopsis thaliana [L.] Heynh) that will be useful for both the identification and structural and functional characterization of homologous proteins from other plant species. and C.B. ); Institute of Plant Biology and Zrich-Basel Plant Science Center, University of Zrich, 8008 Zurich, Switzerland (K.R., C.B. This data set enables observations of specific subfamily expansions (due to consecutive duplications) in some angiosperms from Brassicaceae and Fabaceae. This locus got its name because it was discovered via the study of transplanted tissue compatibility. Moreover, and unlike GH1-Myb-TRB1 to GH1-Myb-TRB3, they both contain a Myb extension-like sequence different from GH1-Myb-TRB1 to GH1-Myb-TRB3, so their binding preferences may be different. Linker histones are a more divergent group of proteins than core histones. Phylogenetic analysis supports an early separation into three subgroups, which we rename here as follows: (1) H1s; (2) GH1-HMGA/GH1-HMGA-related; and (3) GH1-Myb/GH1-Myb-related. The most distinct structural and functional diversification of plant H1s coincided with the appearance of angiosperms (approximately 140 million years ago) and resulted in two major subtypes that have been maintained ever since: the main and stress-inducible H1s. S1). Most of the identified proteins, including those of the H1-HMGA subgroup, contain additional domains. Importantly, only members of the H1 subgroup possess the characteristic regions of strong positive charge in all C-terminal and most N-terminal domains (Supplemental Fig. The GH1-HMGA/GH1-HMGA-related and GH1-Myb/GH1-Myb-related subgroups could be the end result of such specific selection pressures in the plant kingdom. Type 2 diabetes, formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. The dearth of information and the lack of a coherent phylogeny-based nomenclature of these proteins can lead to misunderstandings regarding their identity and possible relationships, thereby hampering plant chromatin research. Using the SMART tool (Schultz et al., 2000; http://smart.embl-heidelberg.de), we identified 48 Arabidopsis proteins containing AT-hook motifs, 23 of which, unlike typical HMGA members, contain only a single AT hook. Select an analyte from the list below to view products that incorporate it. The truncated GH1 domain detected in AT1G54260 was verified in a similar manner. Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria. Its main purpose is to draw attention to the fact that, in plants, the competition-based removal of H1 from chromatin may be dependent on a more diversified and specialized group of competitors than in animals, suggesting novel plant-specific mechanisms of chromatin regulation. Junqueira's Basic Histology Text and Atlas, 14th Edition. We also have indicated (Supplemental Table S1; Supplemental Fig. How metabolites are involved in this process is largely unknown. government site. and the National Science Centre (grant nos. To try and verify such a possibility, we reexamined the long-held view that Arabidopsis is devoid of canonical HMGA proteins. S1). All records found are included in Table I and Supplemental Table S1 (Fucile et al. The wing structure (from which the name of this family of DNA-binding proteins is derived) lies within the region located C terminally to helix III and is an extended loop joining -strands S2 and S3. The results are included in Supplemental Figure S1. Second are balls of proteins composed of histones, which the DNA wraps around. S1). A scheme linking GH1-based phylogenetic relationships with protein domain architectures within this group is shown in Figure 1. Epigenetic remodelling, especially histone methylation, is highly dynamic during pre-implantation embryogenesis 13,14,15,27,28,29,30. A.J. designed the study; M.K. Histone deacetylation gives a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events Sign in to place orders and checkthe status of your recent orders. S2), beginning immediately adjacent to GH1. wrote the article. H1 (or linker) histones are basic nuclear proteins that possess an evolutionarily conserved nucleosome-binding globular domain, GH1. Nicotinamide adenine dinucleotide (NAD) is a coenzyme central to metabolism.Found in all living cells, NAD is called a dinucleotide because it consists of two nucleotides joined through their phosphate groups. As in bacteria, transcription in eukaryotic cells is controlled by Another GH1-Myb of this species has a strongly changed GH1 domain. However, we detected no peptides unique for the smaller AT1G48610.2 form (i.e. In both analyses, the larger version of AT1G48610 had a higher number of peptides and a higher score than the smaller form (100% and 92% of sequence coverage, respectively). Here, we summarize currently available information, including both published data and the findings of our in silico and high-throughput analyses, and propose a coherent system of phylogeny and structure-based nomenclature and annotation of H1s and other GH1-containing proteins of Arabidopsis (Arabidopsis thaliana). National Library of Medicine The phylogenetic relationships among these variants as well as their structural and functional properties have been relatively well established. We were unable to detect this protein in our T87 nuclear proteome (Supplemental Table S1), but its transcript was present in an Arabidopsis transcriptome derived by RNA sequencing analysis (Supplemental Table S1). } { These data indicate that the larger version of the protein (AT1G48610.1) is the main product of this gene. For proteins assigned previously to the GH1-Myb subfamily yet lacking the Myb domain, nucleotide upstream/downstream sequences of coded genes were verified using both manual translations and data from TAIR gene model and exon confidence ranking system (https://www.arabidopsis.org/download_files/Genes/TAIR10_genome_release/TAIR10_gene_confidence_ranking/DOCUMENTATION_TAIR_Gene_Confidence.pdf). PMC legacy view (2016), Histone H1 variants in Arabidopsis are subject to numerous post-translational modifications, both conserved and previously unknown in histones, suggesting complex functions of H1 in plants, GeneSilico protein structure prediction meta-server, Interactive Tree Of Life v2: online annotation and display of phylogenetic trees made easy, SMART: recent updates, new developments and status in 2015, Marian CO, Bordoli SJ, Goltz M, Santarella RA, Jackson LP, Danilevskaya O, Beckstette M, Meeley R, Bass HW (2003), The maize Single myb histone 1 gene, Smh1, belongs to a novel gene family and encodes a protein that binds telomere DNA repeats in vitro, Multifunctionality of the linker histones: an emerging role for protein-protein interactions, Open and closed: the roles of linker histones in plants and animals, Ozturk N, Singh I, Mehta A, Braun T, Barreto G (2014), HMGA proteins as modulators of chromatin structure during transcriptional activation, Prymakowska-Bosak M, Przewoka MR, Iwkiewicz J, Egierszdorff S, Kura M, Chaubet N, Gigot C, Spiker S, Jerzmanowski A (1996), Histone H1 overexpressed to high level in tobacco affects certain developmental programs but has limited effect on basal cellular functions, Przewloka MR, Wierzbicki AT, Slusarczyk J, Kura M, Grasser KD, Stemmer C, Jerzmanowski A (2002), The drought-inducible histone H1s of tobacco play no role in male sterility linked to alterations in H1 variants, Rutowicz K, Puzio M, Halibart-Puzio J, Lirski M, Kotliski M, Krote MA, Knizewski L, Lange B, Muszewska A, niegowska-wierk K, et al. Given such widespread occurrence, it seems highly probable that, at least in some of the detected loci, TRB1, through its GH1 domain, competes for nucleosome binding with H1s. Incomplete truncated sequences were discarded. Only two proteins, the predicted products of the alternatively spliced At1g48610 gene, contain four AT-hook motifs and no other domain. The major histocompatibility complex (MHC) is a large locus on vertebrate DNA containing a set of closely linked polymorphic genes that code for cell surface proteins essential for the adaptive immune system.These cell surface proteins are called MHC molecules.. We have not found any new GH1-containing proteins in Arabidopsis. Approximate likelihood ratio test SH-like (Shimodaira-Hasegawa-like) branch supports above 50% are shown. Since GH1-Myb-TRB3 is very similar to GH1-Myb-TRB1 and GH1-Myb-TRB2 (all three locate on the same branch of the phylogenetic tree; Supplemental Fig. 1) and for 282 representative plant sequences (Supplemental Fig. Phylogenetic trees were inferred both for Arabidopsis GH1 proteins (Fig. Longdom Publishing SL is one of the leading international publishers of open access journals covering clinical, medical, biological, pharmaceutical sciences as well as engineering, management and technology oriented subjects. Most GFP-like (i.e., -barrel-structured) fluorescent proteins are also preserved in this process (Fig. According to the BAR Toronto database (Toufighi et al., 2005), the expression of At1g48610 is strongest in the central, rib, and peripheral zones of the shoot apical meristem, in pistil tissue primarily consisting of ovaries, and in phloem companion cells at the border of the meristematic and elongation zones of the root. ), the National Science Centre (grant no.

While exception proves the rule, it cannot be excluded that at least some of the above singularities resulted from errors in genome assemblies or gene models. This subgroup comprises five proteins with an additional N-terminal Myb domain accompanied by a 17- to 18-amino acid-long Myb extension-like domain. The rapid diversification of the latter compared with the H1s suggests that it was not initially subjected to strong purifying selection but might have been important for the ongoing adaptive evolution of plants. and transmitted securely. a protein with a GH1 domain flanked by two unstructured and highly basic tails) are fulfilled by the products of only three Arabidopsis genes, designated H1.1, H1.2, and H1.3 (Wierzbicki and Jerzmanowski, 2005). Numerous plant GH1-containing proteins are listed as putative or lack any description. The majority of these loci contained telobox-related motifs located at the transcription start sites, with additional loci spreading across gene bodies as well as distal promoter regions. The MSD product line offers a diverse menu of assay kits for profiling cytokines, cell signaling pathways, and other biomarkers. C/EBPs play important roles in various physiological processes, and their abnormal function can lead to various diseases. Moreover, in the maize H1 group, there is a protein with two AT-hook motifs (indicative that such fusions are not unusual in plants). The regions with no detectable homology to known protein domains, yet with conserved sequence and predicted secondary structures (with PSIPRED; Jones, 1999), also have been denoted as potential new domains. The chromosome is ~191 megabases in length. Plant H1s exhibit the universal features of the H1 family, including the occurrence of different nonallelic variants and extensive posttranslational modifications (Table I; Supplemental Table S1; Prymakowska-Bosak et al., 1996; Jerzmanowski et al., 2000; Jerzmanowski, 2004; Kotliski et al., 2016). In addition, and similar to core histones, major animal H1 variants undergo extensive posttranslational modifications of different types (Wisniewski et al., 2007), the importance of most of which is unknown. Sequence data from this article can be found are provided in tables, figures and Supplemental Data. float:left; Sequence searches were performed using H1.2, GH1-HMGA2, GH1-Myb-TRB1, and TRB1 from Arabidopsis as queries. Protein sequences were aligned with the local pair iterative algorithm implemented in Mafft (Yamada et al., 2016). Only 22 alpha amino acids appear in the genetic code.. Amino acids can be classified according to the locations of the core structural functional GH1-Myb-TRB1 was identified in our proteomic analysis of Arabidopsis nuclei, while GH1-Myb-TRB2 and GH1-Myb-TRB3 were detected below the established threshold (Supplemental Table S1). The above notwithstanding, the impression of a seemingly limited diversification of H1s during the evolution of plants may be misleading and result from biased classification rules. This gene encodes the pro-alpha1 chains of type I collagen whose triple helix comprises two alpha1 chains and one alpha2 chain. Surprisingly given the fundamental functions of HMGA proteins in animals, the functional significance of the GH1/multiple AT-hook motif fusion has never been studied, despite its being referred to in all the major literature concerning plant HMG proteins. Universal - SECTOR 600/6000/2400 - QuickPlex SQ 120 (446) SECTOR Imager 6000 (165) Bacterial chromatin does not contain basic histone proteins, but low-molecular-weight polyamines and magnesium ions may fulfill a function similar to that of eukaryotic histones. about navigating our updated article layout. Meso Scale Discovery assays provide a rapid and convenient method for measuring the levels of targets within a single, smallvolume sample. 31003A_149974/1 to C.B.). The demonstration of in vivo interactions of these proteins with Arabidopsis telomerase supports a suggestion that they are part of the greater plant telomeric interactome (Schrumpfov et al., 2014). Phosphorylation alters the structural conformation of a protein, causing it to become either activated or deactivated, or otherwise modifying its function. Federal government websites often end in .gov or .mil. They perform critical functions in determining the accessibility of chromatin DNA to trans-acting factors.
