Involved in centriole duplication. Positively regulates CEP63 centrosomal localization. Required for WDR62 centrosomal localization and promotes the centrosomal localization of CDK2. May play a role in cilium assembly. Interacts with CEP63 and WDR62 (By similarity). Forms a complex with OFD1 and CEP20/FOR20 (PubMed:26643951). Interacts with PCM1 (PubMed:26643951). Extended N-terminus.
