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.
The gene CEP55 (Centrosomal protein of 55kDa) encodes a protein th at 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 3μ-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.
