Description

apc-2 encodes an ortholog of subunit 2 of anaphase-promoting complex (APC, a cyclin-specific E3 RING ubiquitin ligase); APC-2 and S. cerevisiae's Apc2p have 32% identity in their cullin domains (considered crucial for function), but otherwise share no obvious similarity; inactivating apc-2 with RNAi causes embryos to arrest at the meiotic one-cell stage, implying that APC-2 is required for the metaphase-to-anaphase transition of meiosis I; this RNAi phenotype of apc-2 is shared by apc-1, apc-4, apc-11, cdc-16, cdc-23, and cdc-27; by analogy with other APC subunits with hypomorphic alleles, APC-2 is likely to be required for asymmetrical segregation of cell fate determinants in two-cell embryos.
