Protein: Centrosomal protein of 152 kDa (Cep152) (A2AUM9)
Organism: Mus musculus (Mouse)
Function: 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 (By similarity). Acts as a molecular scaffold facilitating the interaction of PLK4 and CENPJ, 2 molecules involved in centriole formation (By similarity). 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 (By similarity). Also plays a key role in deuterosome-mediated centriole amplification in multiciliated that can generate more than 100 centrioles. Overexpression of cep152 can drive amplification of centrioles.
Subcellular location: Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000250|UniProtKB:O94986}. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole {ECO:0000250|UniProtKB:O94986}. Note=Colocalizes with CDK5RAP2, WDR62 and CEP63 in a discrete ring around the proximal end of the parental centriole (By similarity). At this site, a cohesive structure is predicted to engage parental centrioles and procentrioles (By similarity). Localizes to the deuterosome (PubMed:24240477). Localizes to pericentriolar material (PCM) (By similarity). {ECO:0000250|UniProtKB:O94986, ECO:0000269|PubMed:24240477}.
