Background Information
CEP55, also named as C10orf3 and URCC6, is a 55 kDa protein which located in the centrosome in interphase cells and recruited to the midbody during cytokinesis, is essential for completion of cell abscission. It plays a role in mitotic exit and cytokinesis.CEP55 has two isoforms with the MW of 47 and 55 kDa.
