Probable component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle (By similarity). The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins (By similarity). Developmental role in early embryogenesis and the metaphase to anaphase transition in oocyte and spermatocyte meiosis and mitosis in germ cells (PubMed:12620985, PubMed:11134076). Required for embryonic anterior-posterior axis formation (PubMed:11832245). Plays a role in regulating the abundance of glr-1 receptors in postmitotic neurons, which may in turn control animal locomotion (PubMed:15556870). Protein modification; protein ubiquitination. The APC/C complex 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. Expressed in the ventral nerve cord. RNAi-mediated knockdown results in defective metaphase to anaphase transition (Mat phenotype) and embryos that arrest at the one-cell stage. Belongs to the APC3/CDC27 family.
