General description

CENP-A is a variant version of histone H3 found only at centromeres. It is phosphorylated at serine 7 during mitosis.
Centromere protein A (CENP-A) is a 17 kDa centromere-specific histone variant with 62% amino acids homology to the C-terminal of histone H3. Localized in the centromere, it plays a central role in the centromere-specific chromatin formation. The depletion of histone H3 at the CENP-A binding domain suggests CENP-A to be a possible replacement for histone H3 in the packaging process of α-satellite DNA into primary chromation structure. CENP-A is essential in the formation of specialized nucleosomes at the centromere, implicating CENP-A as a centromere-specific epigenetic marker.

Specificity

CENP-A phosphorylated on serine 7
Others not tested.

Immunogen

peptide containing the sequence RRpSRK in which pS is phospho-serine corresponding to amino acid 7 of human CENP-A (centromere protein A)
