Background

Function：Histone H3-like nucleosomal protein that is specifically found in centromeric nucleosomes (PubMed:11756469, PubMed:14667408, PubMed:15282608, PubMed:15475964, PubMed:15702419, PubMed:17651496, PubMed:19114591, PubMed:20739937, PubMed:27499292, PubMed:7962047, PubMed:9024683). Replaces conventional H3 in the nucleosome core of centromeric chromatin that serves as an assembly site for the inner kinetochore (PubMed:18072184). The presence of CENPA subtly modifies the nucleosome structure and the way DNA is wrapped around the nucleosome and gives rise to protruding DNA ends that are less well-ordered and rigid compared to nucleosomes containing histone H3 (PubMed:26878239, PubMed:27499292). May serve as an epigenetic mark that propagates centromere identity through replication and cell division (PubMed:15282608, PubMed:15475964, PubMed:20739937, PubMed:21478274, PubMed:26878239). Required for recruitment and assembly of kinetochore proteins, and as a consequence required for progress through mitosis, chromosome segregation and cytokinesis (PubMed:11756469, PubMed:14667408, PubMed:18072184, PubMed:23818633, PubMed:25556658, PubMed:27499292)

Subcellular Localization：Nucleus; Chromosome, centromere

Isoforms & Post-Translational Modification：P49450 has 2 isomers: P49450-1: 15991 Da (predicted); P49450-2: 13001 Da (predicted).
Ubiquitinated (Probable). Interaction with herpes virus HSV-1 ICP0 protein, leads to its degradation by the proteasome pathway;Trimethylated by NTMT1 at the N-terminal glycine after cleavage of Met-1. Methylation is low before incorporation into nucleosomes and increases with cell cycle progression, with the highest levels in mitotic nucleosomes;Phosphorylated by CDK1 at Ser-68 during early mitosis; this abolishes association with chromatin and centromeres, prevents interaction with HJURP and thereby prevents premature assembly of CENPA into centromeres (PubMed:25556658). Dephosphorylated at Ser-68 by PPP1CA during late mitosis (PubMed:25556658). Phosphorylation of Ser-7 by AURKA and AURKB during prophase is required for localization of AURKA and AURKB at inner centromere and is essential for normal cytokinesis (PubMed:11756469, PubMed:14667408, PubMed:18239465). Initial phosphorylation during prophase is mediated by AURKA and is maintained by AURKB;Poly-ADP-ribosylated by PARP1

Subunit：Component of centromeric nucleosomes, where DNA is wrapped around a histone octamer core (PubMed:20739937, PubMed:21743476, PubMed:23818633, PubMed:26878239). The octamer contains two molecules each of H2A, H2B, CENPA and H4 assembled in one CENPA-H4 heterotetramer and two H2A-H2B heterodimers (PubMed:20739937, PubMed:21743476, PubMed:23818633, PubMed:26878239). CENPA modulates the DNA-binding characteristics of nucleosomes so that protruding DNA ends have higher flexibility than in nucleosomes containing conventional histone H3 (PubMed:21743476, PubMed:27499292). Inhibits binding of histone H1 to nucleosomes, since histone H1 binds preferentially to rigid DNA linkers that protrude from nucleosomes (PubMed:27499292). Nucleosomes containing CENPA also contain histone H2A variants such as MACROH2A and H2A.Z/H2AZ1 (Probable). The CENPA-H4 heterotetramer is more compact and structurally more rigid than corresponding H3-H4 heterotetramers (PubMed:15282608, PubMed:20739937). Can assemble into nucleosomes that contain both CENPA and histone H3.3; these nucleosomes interact with a single CENPC chain (PubMed:25408271). Heterotrimer composed of HJURP, CENPA and histone H4, where HJURP interacts with the dimer formed by CENPA and histone H4 and prevents tetramerization of CENPA and H4 (PubMed:21478274). Component of the CENPA-NAC complex, at least composed of CENPA, CENPC, CENPH, CENPM, CENPN, CENPT and CENPU (PubMed:16622419). Interacts (via CATD domain) with HJURP; the interaction is direct and is required for its localization to centromeres (PubMed:15282608, PubMed:19410544, PubMed:19410545, PubMed:23818633, PubMed:25556658). Interacts with CENPC, CENPN and CENPT; interaction is direct. Part of a centromere complex consisting of CENPA, CENPT and CENPW (PubMed:19533040). Identified in centromere complexes containing histones H2A, H2B and H4, and at least CENPA, CENPB, CENPC, CENPT, CENPN, HJURP, SUPT16H, SSRP1 and RSF1 (PubMed:27499292). Can self-associate (PubMed:9024683). The CENPA-H4 heterotetramer can bind DNA by itself (in vitro) (PubMed:20739937). Interacts with CDK1, PPP1CA and RBBP7 (PubMed:25556658)
