Protein: Centrosome-associated protein CEP250 (250 kDa centrosomal protein) (Cep250) (Centrosomal Nek2-associated protein 1) (C-Nap1) (Centrosomal protein 2) (Q9BV73)
Organism: Homo sapiens (Human)
Function: May be involved in ciliogenesis. Probably plays an important role in centrosome cohesion during interphase. Recruits CCDC102B to the proximal ends of centrioles.
Subcellular location: Cytoplasm, perinuclear region {ECO:0000269|PubMed:9647649}. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome, centriole {ECO:0000269|PubMed:26337392, ECO:0000269|PubMed:30404835, ECO:0000269|PubMed:36282799, ECO:0000269|PubMed:9647649}. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000269|PubMed:14654843, ECO:0000269|PubMed:31974111}. Cytoplasm, cytoskeleton, cilium basal body {ECO:0000269|PubMed:9647649}. Cell projection, cilium, photoreceptor outer segment {ECO:0000250|UniProtKB:Q60952}. Photoreceptor inner segment {ECO:0000250|UniProtKB:Q60952}. Note=Component of the core centrosome. In interphase cells, it specifically associates with the proximal ends of both mother and daughter centrioles. Associates with the centrosome in interphase cells. In mitotic cells, it dissociates from the mitotic spindle poles. At the end of cell division, it reaccumulates at centrosomes.
