Cell 0:0-0(2019). CC -!- FUNCTION: Core component of nucleosome. Nucleosomes wrap and compact CC DNA into chromatin, limiting DNA accessibility to the cellular CC machineries which require DNA as a template. Histones thereby play a CC central role in transcription regulation, DNA repair, DNA replication CC and chromosomal stability. DNA accessibility is regulated via a complex CC set of post-translational modifications of histones, also called CC histone code, and nucleosome remodeling. CC -!- SUBUNIT: The nucleosome is a histone octamer containing two molecules CC each of H2A, H2B, H3 and H4 assembled in one H3-H4 heterotetramer and CC two H2A-H2B heterodimers. The octamer wraps approximately 147 bp of CC DNA. CC -!- SUBCELLULAR LOCATION: Nucleus. Chromosome. CC -!- PTM: Deiminated on Arg-4 in granulocytes upon calcium entry. CC {ECO:0000269|PubMed:15823041}. CC -!- PTM: Monoubiquitination of Lys-120 (H2AK119Ub) by RING1, TRIM37 and CC RNF2/RING2 complex gives a specific tag for epigenetic transcriptional CC repression and participates in X chromosome inactivation of female CC mammals. It is involved in the initiation of both imprinted and random CC X inactivation. Ubiquitinated H2A is enriched in inactive X chromosome CC chromatin. Ubiquitination of H2A functions downstream of methylation of CC 'Lys-27' of histone H3 (H3K27me). H2AK119Ub by RNF2/RING2 can also be CC induced by ultraviolet and may be involved in DNA repair. CC Monoubiquitination of Lys-120 (H2AK119Ub) by TRIM37 may promote CC transformation of cells in a number of breast cancers CC (PubMed:25470042). Following DNA double-strand breaks (DSBs), it is CC ubiquitinated through 'Lys-63' linkage of ubiquitin moieties by the E2 CC ligase UBE2N and the E3 ligases RNF8 and RNF168, leading to the CC recruitment of repair proteins to sites of DNA damage. Ubiquitination CC at Lys-14 and Lys-16 (H2AK13Ub and H2AK15Ub, respectively) in response CC to DNA damage is initiated by RNF168 that mediates monoubiquitination CC at these 2 sites, and 'Lys-63'-linked ubiquitin are then conjugated to CC monoubiquitin; RNF8 is able to extend 'Lys-63'-linked ubiquitin chains CC in vitro. Deubiquitinated by USP51 at Lys-14 and Lys-16 (H2AK13Ub and CC H2AK15Ub, respectively) after damaged DNA is repaired CC (PubMed:27083998). H2AK119Ub and ionizing radiation-induced 'Lys-63'- CC linked ubiquitination (H2AK13Ub and H2AK15Ub) are distinct events.

CC -!- PTM: Phosphorylation on Ser-2 (H2AS1ph) is enhanced during mitosis. CC Phosphorylation on Ser-2 by RPS6KA5/MSK1 directly represses CC transcription. Acetylation of H3 inhibits Ser-2 phosphorylation by CC RPS6KA5/MSK1. Phosphorylation at Thr-121 (H2AT120ph) by DCAF1 is CC present in the regulatory region of many tumor suppresor genes and CC down-regulates their transcription. {ECO:0000269|PubMed:15010469, CC ECO:0000269|PubMed:15078818, ECO:0000269|PubMed:15823041, CC ECO:0000269|PubMed:16457589, ECO:0000269|PubMed:24140421}. CC -!- PTM: Symmetric dimethylation on Arg-4 by the PRDM1/PRMT5 complex may CC play a crucial role in the germ-cell lineage. CC {ECO:0000250|UniProtKB:P22752}. CC -!- PTM: Glutamine methylation at Gln-105 (H2AQ104me) by FBL is CC specifically dedicated to polymerase I. It is present at 35S ribosomal CC DNA locus and impairs binding of the FACT complex (PubMed:24352239). CC {ECO:0000269|PubMed:24352239}. CC -!- PTM: Crotonylation (Kcr) is specifically present in male germ cells and CC marks testis-specific genes in post-meiotic cells, including X-linked CC genes that escape sex chromosome inactivation in haploid cells. CC Crotonylation marks active promoters and enhancers and confers CC resistance to transcriptional repressors. It is also associated with CC post-meiotically activated genes on autosomes. CC {ECO:0000269|PubMed:21925322}. CC -!- PTM: Lactylated in macrophages by EP300/P300 by using lactoyl-CoA CC directly derived from endogenous or exogenous lactate, leading to CC stimulates gene transcription. {ECO:0000250|UniProtKB:P0C0S5}. CC -!- MASS SPECTROMETRY: Mass=13890.8; Method=Electrospray; Note=Monoisotopic CC with N-acetylserine.; Evidence={ECO:0000269|PubMed:16457589}; CC -!- SIMILARITY: Belongs to the histone H2A family. {ECO:0000305}.
