Centrosomal protein 164 (CEP164) is a centriole appendage protein encoded by the gene mapped to human chromosome 11q23.3. CEP164 is apparently a 164kDa protein composed of 1,460 amino acids and is specifically localized on mature centrioles. The encoded protein mainly contains a putative N-terminal WW domain and three coiled-coil domains.
Synonyms: Anti-KIAA1052; Anti-NPHP15
Storage: -20C
Biochem Physiol Actions: Centrosomal protein 164 (CEP164) plays an essential role in primary cilium formation. In addition, it also acts as a potential marker for distal appendages on mature centrioles or basal bodies. Mutation in the gene is associated with early defects in ciliogenesis. CEP164 directs tau tubulin kinase 2 (TTBK2) to the mother centriole and thus stimulates ciliogenesis.
