CENPH, also known as centromere protein H, belongs to the centromere protein H family. This protein is component of the CENPA-NAC (nucleosome-associated) complex that plays a central role in assembly of kinetochore proteins. The CENPA-NAC complex recruits the CENPA-CAD (nucleosome distal) complex and may be involved in incorporation of newly synthesized CENPA into centromeres.
