CCDC63 (Coiled-Coil Domain Containing 63) is a highly conserved centrosomal satellite protein whose main functions are closely related to cell mitosis and ciliogenesis. This protein directly interacts with PCM1, a key organizer of centrosomal satellites, through its coiled-coil domain and is recruited to the pericentriolar material. As an important component of centrosomal satellites, CCDC63 is involved in regulating the normal assembly of the centrosome, microtubule anchoring, and proper orientation of the spindle, thereby ensuring the fidelity of chromosome segregation and genomic stability. Therefore, CCDC63 is one of the core molecules that maintain the accuracy of cell division and the function of organelles.
