Description_x000D_ General description_x000D_ The gene CEP55 (Centrosomal protein of 55kDa), also referred to as C10orf3, encodes a 464 amino acid containing protein with highest expression in testis and thymus. This coiled-coil protein has a molar mass of 55kDa. The gene is mapped to human chromosome 10q23.33._x000D_ Immunogen_x000D_ CEP55 (NP_060601.2, 1 a.a. ~ 464 a.a) full-length human protein._x000D_ Sequence_x000D_ MSSRSTKDLIKSKWGSKPSNSKSETTLEKLKGEIAHLKTSVDEITSGKGKLTDKERHRLLEKIRVLEAEKEKNAYQLTEKDKEIQRLRDQLKARYSTTALLEQLEETTREGERREQVLKALSEEKDVLKQQLSAATSRIAELESKTNTLRLSQTVAPNCFNSSINNIHEMEIQLKDALEKNQQWLVYDQQREVYVKGLLAKIFELEKKTETAAHSLPQQTKKPESEGYLQEEKQKCYNDLLASAKKDLEVERQTITQLSFELSEFRRKYEETQKEVHNLNQLLYSQRRADVQHLEDDRHKTEKIQKLREENDIARGKLEEEKKRSEELLSQVQFLYTSLLKQQEEQTRVALLEQQMQACTLDFENEKLDRQHVQHQLLVILKELRKARNQITQLESLKQLHEFAITEPLVTFQGETENREKVAASPKSPTAALNESLVECPKCNIQYPATEHRDLLVHVEYCSK_x000D_ Physical form_x000D_ Solution in phosphate buffered saline, pH 7.4_x000D_ Biochem/physiol Actions_x000D_ The gene CEP55 (Centrosomal protein of 55kDa) encodes a protein that is found to be localized to the mother centriole during interphase. It plays a crucial role in microtubule nucleation, mitotic exit and cytokinesis. The protein CEP55 also elicits the cell transformation by stimulating the phosphatidylinositol 3′-kinase (PI3K)/AKT pathway. It participates in the regulation of cell-cycle and is found in certain tumor tissues, such as hepatocellular carcinoma and gastric cancer. Additionally, it is also involved in midbody structure during cytokinesis.
