Histone H3-like centromeric protein A

CENPA is a centromere specific histone H3 variant and localizes to the centromeric hetrochromatinised regions of the genome (PMID: 7962047, PMID: 10639145). CENPA is essential for the formation of kinetochores and recruitment of other factors required for spindle assembly (PMID: 11682612). Histone modifications present in the centromeric region are significantly different from the euchromatic or hetrochromatic regions and is supposed to be partly enabled by CENP-A (PMID: 15475964). CENPA is also shown to be recruited at the sites of DNA damage and this event is independent of H2A.X signal (PMID: 19717431). CENPA is incorporated specifically at centromeric region by the coordination of different molecules like nucleophosmin 1, and HJURP (PMID: 19410544).
