Required for mitotic centrosome maturation and bipolar spindle assembly (PubMed:17980596, PubMed:18207742, PubMed:25042804). Appears to be a major regulator of pericentriolar material (PCM) recruitment, centrosome maturation, and centriole duplication (PubMed:17980596, PubMed:18207742, PubMed:25042804). Centrosome- specific activating scaffold for AURKA and PLK1 (PubMed:25042804). {ECO:0000269|PubMed:17980596, ECO:0000269|PubMed:18207742, ECO:0000269|PubMed:25042804}. This is the function of ENSG00000101639 (CEP192, centrosomal protein 192).
