Probable component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins. Developmental role in early embryogenesis and the metaphase to anaphase transition in meiosis and mitosis. Protein modification; protein ubiquitination. The APC/C is probably composed of at least 12 subunits: apc-2, apc-10, apc-11, cdc-26, emb-1, emb-27, emb-30, mat-1, mat-2, mat-3, such-1 and gfi-3. RNAi-mediated knockdown results in defective metaphase to anaphase transition (Mat phenotype) and embryos that arrest at the one-cell stage. Belongs to the cullin family.
