ANTI-C-NAP1 (CEP250) CLONE 150-230-1 (C005B-448628)

General description

Centrosome-associated protein CEP250 (UniProt: Q9BV73; also known as 250 kDa centrosomal protein, Cep250, Centrosomal NEK2-associated protein 1, C-Nap1, Centrosomal protein 2) is encoded by the CEP250 (also known as CEP2, CNAP1) gene (Gene ID: 11190) inn human. Cep250 is a component of the core centrosome that is ubiquitously expressed. It can exist as a monomer and homodimer. It specifically associates with the proximal ends of both mother and daughter centrioles during interphase and in mitotic cells it dissociates from the mitotic spindle poles. At the end of cell division, it is shown to re-accumulate at centrosomes. Cep250 is differentially phosphorylated during cell cycle and phosphorylation status regulates its association/dissociation from centrosome. During M phase its C-terminal part is shown to be phosphorylated by NEK2. Two isoforms of Cep250 have been described that are produced by alternative splicing. Loss of Cep250-mediated centriole cohesion leads to an altered cell migration phenotype.
