Necessary for centrosome duplication; the function seems also to involve CEP63, CDK5RAP2 and WDR62 through a stepwise assembled complex at the centrosome that recruits CDK2 required for centriole duplication (PubMed:26297806). Acts as a molecular scaffold facilitating the interaction of PLK4 and CENPJ, 2 molecules involved in centriole formation (PubMed:21059844, PubMed:20852615). Proposed to snatch PLK4 away from PLK4:CEP92 complexes in early G1 daughter centriole and to reposition PLK4 at the outer boundary of a newly forming CEP152 ring structure (PubMed:24997597). Also plays a key role in deuterosome-mediated centriole amplification in multiciliated that can generate more than 100 centrioles (By similarity). Overexpression of CEP152 can drive amplification of centrioles (PubMed:20852615). Interacts (via N-terminus) with PLK4; the interaction is mutally exclusive with a PLK4:CEP192 interaction (PubMed:21059844, PubMed:20852615, PubMed:24997597). Interacts (via C-terminus) with CENPJ (via-N-terminus) (PubMed:20852615). Interacts with CINP (PubMed:21131973). Interacts with CDK5RAP2, WDR62, CEP63 and CEP131 (PubMed:21983783, PubMed:24613305, PubMed:26297806). CEP63, CDK5RAP2, CEP152, WDR62 are proposed to form a stepwise assembled complex at the centrosome forming a ring near parental centrioles (PubMed:26297806). Interacts with DEUP1; this interaction recruits CEP152 to the deuterosome. The interactions with CEP63 and DEUP1 are mutually exclusive (By similarity). Colocalizes with CDK5RAP2, WDR62 and CEP63 in a discrete ring around the proximal end of the parental centriole. At this site, a cohesive structure is predicted to engage parental centrioles and procentrioles (PubMed:21983783, PubMed:26297806). Localizes to the deuterosome (By similarity). Localizes to pericentriolar material (PCM) (PubMed:26337392). The disease is caused by variants affecting the gene represented in this entry. The disease is caused by variants affecting the gene represented in this entry. Belongs to the CEP152 family. Contaminating sequence. Potential poly-A sequence. Extended N-terminus.
