UniProtKB - O43303 (CP110_HUMAN)

Protein

Centriolar coiled-coil protein of 110 kDa

Gene

CCP110

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Necessary for centrosome duplication at different stages of procentriole formation. Acts as a key negative regulator of ciliogenesis in collaboration with CEP97 by capping the mother centriole thereby preventing cilia formation (PubMed:17719545 PubMed:17681131, PubMed:23486064). Also involved in promoting ciliogenesis. May play a role in the assembly of the mother centriole subdistal appendages (SDA) thereby effecting the fusion of recycling endosomes to basal bodies during cilia formation (By similarity). Required for correct spindle formation and has a role in regulating cytokinesis and genome stability via cooperation with CALM1 and CETN2 (PubMed:16760425).By similarity5 Publications

Phosphorylated by CDKs.1 Publication
Ubiquitinated by the SCF(CCNF) during G2 phase, leading to its degradation by the proteasome and preventing centrosome reduplication. Deubiquitinated by USP33 in S and G2/M phase, leading to stabilize CCP110 during the period which centrioles duplicate and elongate.2 Publications

Highly expressed in testis. Detected at intermediate levels in spleen, thymus, prostate, small intestine, colon and peripheral blood leukocytes.1 Publication

Up-regulated during the transition from G1 to S phase of the cell cycle. The highest levels are observed in S phase, after which the levels decrease markedly.1 Publication

Interactioni

Subunit structurei

Interacts with CALM1, CETN2, CEP76, CEP97, CEP104, CEP290, TALPID3. Seems to associate with discrete CETN2, CEP97 and CEP290-containing complexes. Interacts with NEURL4 and CCNF; these interactions are not mutually exclusive and both lead to CCP110 ubiquitination and proteasome-dependent degradation. Via its interaction with NEURL4, may indirectly interact with HERC2. Interacts with KIF24, leading to its recruitment to centrioles. Interacts with USP20 and USP33.11 Publications
