Involved in centriole duplication (PubMed:24613305, PubMed:26297806). Positively regulates CEP63 centrosomal localization (PubMed:24613305, PubMed:26297806). Required for WDR62 centrosomal localization and promotes the centrosomal localization of CDK2 (PubMed:24613305, PubMed:26297806). May play a role in cilium assembly. Interacts with CEP63 (PubMed:24613305). Interacts with WDR62 (PubMed:26297806). Forms a complex with OFD1 and CEP20/FOR20 (PubMed:26643951). Interacts with PCM1 (PubMed:26297806, PubMed:26643951). Localization to centrioles and pericentriolar satellites may be mediated by interaction with PCM1. The disease may be caused by variants affecting the gene represented in this entry. The disease may be caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. Extended N-terminus.
