[[Centromeres]] are the chromosomal domains that specify the mitotic behavior of chromosomes. The CENPA gene 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 [[isoform]]s.<ref name="gene uid 1058"/> | |||
In higher eukaryotes, the recruitment of CENP-A nucleosomes to existing centromeres is an epigenetic process, independent of the underlying DNA sequence. In ''S. pombe'', de novo recruitment of the CENP-A to the centromere is believed to be controlled by "centromeric" [[heterochromatin]] surrounding the centromere, and by an [[RNAi]] mechanism. The RNAi is cut to form [[siRNA]]; this complexes with the protein Chp1, which then binds the centromeric heterochromatin. This helps recruit other proteins, ultimately resulting in a protein complex that forms [[cohesin]] between two [[sister chromatids]] at the centromeric heterochromatin. This cohesin is believed to be essential in replacing the centromere H3 with CENP-A. CENP-A is one of the [[epigenetic]] changes that is believed to distinguish centromeric DNA from other DNA.<ref name="pmid15537667">{{cite journal | vauthors = Chueh AC, Wong LH, Wong N, Choo KH | title = Variable and hierarchical size distribution of L1-retroelement-enriched CENP-A clusters within a functional human neocentromere | journal = Hum.

Centromere protein A, also known as CENPA, is a protein which in humans is encoded by the CENPA gene.[1]
Function
Centromeres are the chromosomal domains that specify the mitotic behavior of chromosomes. The CENPA gene 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.[1]
In higher eukaryotes, the recruitment of CENP-A nucleosomes to existing centromeres is an epigenetic process, independent of the underlying DNA sequence. In S. pombe, de novo recruitment of the CENP-A to the centromere is believed to be controlled by "centromeric" heterochromatin surrounding the centromere, and by an RNAi mechanism. The RNAi is cut to form siRNA; this complexes with the protein Chp1, which then binds the centromeric heterochromatin. This helps recruit other proteins, ultimately resulting in a protein complex that forms cohesin between two sister chromatids at the centromeric heterochromatin. This cohesin is believed to be essential in replacing the centromere H3 with CENP-A. CENP-A is one of the epigenetic changes that is believed to distinguish centromeric DNA from other DNA.[2] Once the CENP-A has been added, the centromere becomes self-propagating, and the surrounding heterochromatin/RNAi mechanism is no longer necessary.[3]
