background: Centromeres are the differentiated chromosomal domains that specify the mitotic behavior of chromosomes. CENPA encodes a centromere protein which contains a histone H3 related histone fold domain that is required for targeting to the centromere. CENPA is proposed to be a component of a modified nucleosome or nucleosome-like structure in which it replaces 1 or both copies of conventional histone H3 in the (H3-H4)2 tetrameric core of the nucleosome particle. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq]. Function: Histone H3-like variant which exclusively replaces conventional H3 in the nucleosome core of centromeric chromatin at the inner plate of the kinetochore. Required for recruitment and assembly of kinetochore proteins, mitotic progression and chromosome segregation. May serve as an epigenetic mark that propagates centromere identity through replication and cell division. The CENPA-H4 heterotetramer can bind DNA by itself (in vitro). Subunit: Forms a nucleosome-like histone octamer containing two molecules each of H2A, H2B, CENPA and H4 assembled in one CENPA-H4 heterotetramer and two H2A-H2B heterodimers. Nucleosomes containing CENPA also contain histone H2A variants such as macroH2A H2AFY and H2A.Z/H2AFZ. The CENPA-H4 heterotetramer is more compact and structurally more rigid than corresponding H3-H4 heterotetramers. 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. Component of the CENPA-NAC complex, at least composed of CENPA, CENPC, CENPH, CENPM, CENPN, CENPT and MLF1IP/CENPU. Interacts (via CATD domain) with HJURP; the interaction is direct and is required for its localization to centromeres. Interacts with CENPC, CENPN and CENPT; interaction is direct. Interacts directly with herpes virus HSV-1 ICP0 protein. Part of a centromere complex consisting of CENPA, CENPT and CENPW. Subcellular Location: Nucleus. Chromosome, centromere, kinetochore. Note=Localizes exclusively in the kinetochore domain of centromeres. Occupies a compact domain at the inner kinetochore plate stretching across 2 thirds of the length of the constriction but encompassing only one third of the constriction width and height. Tissue Specificity: Ubiquitinated (Probable). Interaction with herpes virus HSV-1 ICP0 protein, leads to its degradation by the proteasome pathway. 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 kinetochore function. Initial phosphorylation during prophase is mediated by AURKA and is maintained by AURKB. Poly-ADP-ribosylated by PARP1. Similarity: Belongs to the histone H3 family.

CENP-A可將著絲粒變成一個(gè)DNA和蛋白的復(fù)合物，而且確保著絲粒在細(xì)胞分裂中完好無損。 CENP-A的存在確保了人體有幾乎完全相同的染色體組。 CENP-A功能失常將導(dǎo)致細(xì)胞分裂過程中發(fā)生染色體分離異常。 CENP-A對于染色體著絲粒的位置起決定作用，因而被認(rèn)為是重要的表觀遺傳學(xué)標(biāo)記蛋白。 CENP-A改變了核小體的性狀，使得它變得更加堅(jiān)硬。核小體是由DNA與組合蛋白八聚體構(gòu)成的真核染色體的一種重復(fù)結(jié)構(gòu)，核小體的組織對于基因調(diào)控極為重要。不同于染色質(zhì)上的其他區(qū)域。 CENP-A取代組蛋白H3形成核小體，CENP-A核小體重復(fù)拷貝形成一個(gè)特異的表觀遺傳區(qū)域。 |
