Component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin-protein ligase complex that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex controls several key steps in the cell cycle by mediating the ubiquitination and subsequent degradation of target proteins such as cyclins. The APC/C complex is required for the female gametophyte development and is involved in several other aspects of development. Involved in the control of endoreduplication. Protein modification; protein ubiquitination. Component of the anaphase promoting complex/cyclosome (APC/C), which is composed of at least 10 subunits. Interacts with CDC20-1, CDC20-2, CDC27A and CDC27B. Belongs to the APC10 family.
