View All» Modifications: Ubiquitylation View All» Clone: E6C5 View All» Isotype: IgM View All» Background Information: Histones are highly conserved proteins that serve as the structural scaffold for the organization of nuclear DNA into chromatin. Histones are modified post-translationally by acetylation, phosphorylation, methylation, and ubiquitination and these modifications regulate DNA transcription, repair, recombination, and replication. Ubiquitylation usually targets the substrate for degradation, although histones H2A and H2B are actually stabilized by a single ubiquitin conjugation. Histone ubiquitination has been correlated with DNA repair and transcription, cellular differentiation, cell cycle regulation, spermatogenesis, protein trafficking, and response to stress. Histone H2A is monoubiquitinated at Lys119 by the PRC-1L complex (Polycomb repressive complex 1-like), which includes Ring1, Ring2, Bmi1 and HPH2. Ubiquitinated H2A normally represents about 15% of H2A, but this value can be as high as 50% in active chromatin. Ubiquitinyl histone H2A has also been associated with transcriptional silencing of large chromatin regions and linked to Polycomb silencing so the function of ubiquitinated H2A remains undefined.

        View All» Entrez Gene Summary: Histones are basic nuclear proteins that are responsible for the nucleosome structure of the chromosomal fiber in eukaryotes. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form an octamer, around which approximately 146 bp of DNA is wrapped in repeating units, called nucleosomes. The linker histone, H1, interacts with linker DNA between nucleosomes and functions in the compaction of chromatin into higher order structures. This gene is intronless and encodes a member of the histone H2A family. [provided by RefSeq]. View All» UniProt Summary: FUNCTION: SwissProt: Q96QV6 # Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.SIZE: 131 amino acids; 14234 Da SUBUNIT: The nucleosome is a histone octamer containing two molecules each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of DNA.SUBCELLULAR LOCATION: Nucleus.PTM: The chromatin-associated form is phosphorylated on Thr-121 during mitosis (Probable). & Deiminated on Arg-4 in granulocytes upon calcium entry. & Monoubiquitination of Lys-120 by RING1 and RNF2/RING2 complex gives a specific tag for epigenetic transcriptional repression and participates in X chromosome inactivation of female mammals. It is involved in the initiation of both imprinted and random X inactivation. Ubiquitinated H2A is enriched in inactive X chromosome chromatin. Ubiquitination of H2A functions downstream of methylation of 'Lys-27' of histone H3. Monoubiquitination of Lys-120 by RNF2/RING2 can also be induced by ultraviolet and may be involved in DNA repair. & Phosphorylation on Ser-2 is enhanced during mitosis. Phosphorylation on Ser-2 by RPS6KA5/MSK1 directly represses transcription. Acetylation of H3 inhibits Ser-2 phosphorylation by RPS6KA5/MSK1. & Symmetric dimethylation on Arg-4 by the PRDM1/PRMT5 complex may play a crucial role in the germ-cell lineage (By similarity).SIMILARITY: SwissProt: Q96QV6 ## Belongs to the histone H2A family.
