General description

Centromere protein A is a protein encoded by the CENPA gene in humans. It is a histone H3 variant that has centromere-specific nucleosomal property and is located at neocentromere found on chromosome 10. CENP-A- binding clusters is associated with nucleosomal blocks within the neocentromeric chromatin.

Physical form

Solution in 0.01 mM phosphate buffered saline, pH 7.4, and 15 mM sodium azide.


Anti-CENP-A (N-terminal) antibody produced in rabbit is suitable for western blotting at a concentration of 0.5-1μg/mL using HEK-293T cells expressing human CENP-A.

Biochem/physiol Actions

The location of the centromere on the chromosome is dependent on the histone H3 variant centromere protein A (CENP-A). The N-terminal tail of CENP-A is highly different from other H3 variants. Serine 7 of CENP-A plays an important role in mitosis-specific phosphorylation. It also plays a key role in kinetochore assembly. Alteration in CENP-A causes various human cancers. CENP-A may play an important role in epithelial ovarian cancer (EOC) and may serve as prognostic marker. It acts as a potential target for gene therapy in the treatment of EOC. The NH2 terminus of human CENP-A is essential for mitotic progression and necessary for the platform function of CENP-A centromeric chromatin in the assembly as well as maintenance of active kinetochores.
