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.
Immunogen
synthetic peptide corresponding to amino acids 124-140 located at the C-terminus of human CENP-A, conjugated to KLH. This sequence is highly conserved (88% identity) in bovine and dog CENP-A, and shows 60% identity with histone H3.
Application
Anti-CENP-A (C-terminal) antibody produced in rabbit is suitable for western blotting at a concentration of 1-2μg/mL using HEK-293 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.

Altered expression of centromere protein-A (CENP-A) is observed in various types of human cancers. However, the clinical significance and pathological role of CENP-A in epithelial ovarian cancer (EOC) remains unclear. The main objective of this investigation was to clarify the

Serine 7 of centromere protein A (CENP-A) is a very important mitosis-specific phosphorylation site. In this study, we demonstrate the subcellular distribution of Ser7 phosphorylated CENP-A during mitosis in MCF-7 cells. The Ser7 phosphorylation of CENP-A was observed beginning at

Centromeres are chromosomal loci required for accurate segregation of sister chromatids during mitosis. The location of the centromere on the chromosome is not dependent on DNA sequence, but rather it is epigenetically specified by the histone H3 variant centromere protein

Human neocentromeres are fully functional centromeres that arise epigenetically from non-centromeric precursor sequences that are devoid of alpha-satellite DNA. Using chromatin immunoprecipitation (ChIP) and BAC-array analysis, we have previously described a 330 kb binding domain for CENP-A (a histone H3

Heterochromatin is defined by distinct posttranslational modifications on histones, such as methylation of histone H3 at lysine 9 (H3K9), which allows heterochromatin protein 1 (HP1)-related chromodomain proteins to bind. Heterochromatin is frequently found near CENP-A chromatin, which is the key
