Huge variety of modified histone Over 80 % of nucleosomes contain the linker Histone H1, derived from an intronless gene that interacts with linker DNA between nucleosomes and mediates compaction into higher order chromatin. Histones are subject to posttranslational modification by enzymes primarily on their N-terminal tails, but also in their globular domains Histone 1 (H1) is a protein located in nuclei, incorporated into chromatin. Product citations. Selected references Benoit et al. (2018). Replication-coupled histone. Histone H1. Histone H1 is a group of one of the most well studied histone variants till date. They are about 21 to 29 kDa proteins consisting of 194-255 amino acid residues depending on the variant. H1 is a linker histone which binds to the 'nucleosome' from outside and facilitates further compaction of chromatin We present evidence that chordate protamines have evolved from histone H1. During the final stages of spermatogenesis, the compaction of DNA in many organisms is accomplished by the replacement of histones with a class of arginine-rich proteins called protamines. In other organisms, however.

Histone H1 phosphorylation affects chromatin condensation and function, but little is known about how specific phosphorylations impact the function of H1 variants in higher eukaryotes. In this study, we show that specific sites in H1.2 and H1.4 of human cells are phosphorylated only during mitosis or during both mitosis and interphase Linker histone H1 is an essential component of chromatin structure. H1 links nucleosomes into higher order structures. Histone H5 performs the same function as histone H1, and replaces H1 in certain cells. The structure of GH5, the globular domain of the linker histone H5 is known [PMID: 8384699, PMID: 3463990]. The fold is similar to the DNA. Histone H1.5 is differentially distributed in hESCs and fibroblasts. To determine whether the genomic distribution of H1.5 is different in hESCs versus fibroblasts, we used chromatin immunoprecipitation combined with sequencing (ChIP-seq) of linker histone H1.5 in H1 hESCs and human lung IMR90 fibroblasts The results of real-time PCR showed that histone H1.3 was efficiently silenced (Supplementary Fig. S9). Partial rescue of inhibition of cell proliferation by histone H1.3 knockdown was observed starting from passage 2 . The longer latency of the rescue effect in these cells may have been caused by the relatively longer half-life of histone. However, the simultaneous ectopic expression of hemagglutinin-tagged HMGA2 and N-terminally EGFP-tagged histone H1 leads to significant SAHF formation (P < 0.001). It is known that histone H1 and HMG proteins compete for a common binding site, the linker DNA

The genes encoding H1 histones are evolutionarily less well conserved than those that encode the core histones, but similar lysine-rich, positively charged proteins are found in organisms as diverse as fungi and protoctists, indicating that the role of the 'linker' histone is well conserved Background and Aim: Histone H1.5 (HH1.5) is a subtype of histone H1, a family of linker proteins that is known to determine chromatin structure, alter gene expression and DNA repair. It also contributes to regulation of cell proliferation in breast cancer Histone proteins are among the most highly conserved proteins in eukaryotes, which suggests they are vital to the biology of the nucleus.:939 In contrast, mature sperm cells largely use protamines to package their genomic DNA, most likely to achieve an even higher packaging ratio

HIST1H1C - Histone H1

Abstract. Among various histones, histone H1 proteins have been appreciated for their multiple functions in diverse biological processes. In addition to being a structural protein in chromatin, H1 proteins also play critical roles in cell cycle, gene expression, and development Histone H1 antibody worked well on rat cell extracts and detected a single band of expected size for histone H1 at ~30KDa. Also detected a smaller species of 10-12KDa, perhaps histone H4 Role of Linker Histone H1 in Epigenetic Gene Regulation Project Summary Epigenetic mechanisms are crucial for chromatin structure reprogramming and gene expression during mammalian development and cell differentiation The linker histone H1 has a key role in establishing and maintaining higher order chromatin structure and in regulating gene expression. Mammals express up to 11 different H1 variants, with H1.2 and H1.4 being the predominant ones in most somatic cells

plays a global role in chromatin compaction in vivo by promoting the association of the linker histone H1 with chromatin. Citation: Corona DFV, Siriaco G, Armstrong JA, Snarskaya N, McClymont SA, et al. (2007) ISWI regulates higher-order chromatin structure and histone H1 assembly in vivo Linker histone H1 is a highly abundant chromatin architectural protein with about 1 linker histone per nucleosome in human somatic cells. H1 binds to both DNA between nucleosomes (linker DNA) and near the dyad symmetry axis of the nucleosomes. H1 binding increases DNA wrapping within the nucleosome and compacts chromatin In which taxa did H1 linker histones appear in the course of evolution? Detailed comparative analysis of the histone H1 and histone H1-related sequences available to date suggests that the origin of histone H1 can be traced to bacteria Histone H1.0 belongs to the class of linker histones (H1), although it is substantially distinct from other histone H1 family members. The differences can be observed in the chromosomal location and organization of the histone H1.0 encoding gene, as well as in the length and composition of its amino acid chain
