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). Required for the metaphase to anaphase transition in meiosis (PubMed:17237515, PubMed:20944012). Plays a role in the segregation of DNA and centrioles during meiosis in male germ cells (PubMed:20944014). 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 head neurons, vulval precursor cells and in mature sperm stored in the spermatheca. Expressed in the developing germ line and throughout embryogenesis. Double RNAi-mediated knockdown and/or mutagenesis with gfi-3 results in increased embryonic lethality and the production of one-cell arrested embryos. Belongs to the APC5 family.
