Purified anti-APC10

APC10 (anaphase-promoting complex subunit 10) is a member of the E3 enzyme family. This protein contains a Doc domain and has a molecular weight of approximately 21 kD. The APC10 protein is located at the centrosomes and mitotic spindles throughout mitosis and the kinetochores from prophase to anaphase, and at the midbody during telophase and cytokinesis. The APC10 protein is involved in substrate recognition and acts as a processivity factor. The APC10 protein functions with other members of the APC complex as a multisubunit cell cycle ubiquitin ligase, and a regulator of sister chromatid separation by degrading securins. In addition, this protein functions in ubiquitin-dependent cyclin catabolism, metaphase/anaphase transition, and spindle elongation. The APC10 protein comprises one subunit of the anaphase promoting complex including APC1-8, and other probable complex proteins APC9-11, Cdc26, Mnd2, Swm1. The APC complex is inactivated by protein kinase A and is activated by CDC20 and Cdh1. The Poly6115 antibody has been shown to be useful for Western blotting of the human and mouse APC10 protein.
