The CCP110 gene encodes a protein involved in key cellular processes such as centrosome duplication, spindle formation and the regulation of cytokinesis. CCP110 acts as a negative regulator of ciliogenesis by interacting with CEP97 to cap the mother centriole. The protein is also capable of positively regulating cilium assembly. CCP110 is further involved in several biological processes such as centriole replication, ciliary basal body docking and organization, as well as G2/M transition of mitotic cell cycle.
