Apc10: Proteins and Enzymes

APC is a ubiquitin ligase which specifically targets mitotic regulatory factors such as Pds 1/Cut 2 and cyclin B. It was found that APC 10/Doc 1 is localized in centrosomes and mitotic spindles throughout mitosis, while it is also localized in kinetochores from prophase to anaphase and in mid body in telophase and cytokinesis. These results strongly support the notion that human APC 10/Doc 1 may be one of the APC core subunits rather than the transiently associated regulatory factor.
