Method: Electron Microscopy, Resolution 3.42Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function H31_HUMAN CENPA_CHICK Histone H3-like nucleosomal protein that is specifically found in centromeric nucleosomes (PubMed:14563550). Replaces conventional H3 in the nucleosome core of centromeric chromatin that serves as an assembly site for the inner kinetochore. The presence of CENPA subtly modifies the nucleosome structure and the way DNA is wrapped around the nucleosome and gives rise to protruding DNA ends that are less well-ordered and rigid compared to nucleosomes containing histone H3. May serve as an epigenetic mark that propagates centromere identity through replication and cell division (By similarity). Required for recruitment and assembly of kinetochore proteins, and as a consequence required for progress through mitosis, chromosome segregation and cytokinesis (PubMed:15870271).[UniProtKB:P49450] See Also Histone 3D structures
