Immunofluorescent analysis of Phospho-CENP-A pSer7 in a mitotic HeLa cell using a Phospho-CENP-A pSer7 polyclonal antibody (Product # PA5-17195) (green) and a beta-Tubulin monoclonal antibody (red). Phospho-CENP-A signal is localized to bright spots in the metaphase plate. DNA is labeled using a fluorescent blue dye.

This antibody is not cross-reactive with other histone proteins, including Histone H3.
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.
