DESCRIPTION

Also known as CDC20_HUMAN, CDC20. Required for full ubiquitin ligase activity of the anaphase promoting complex/cyclosome (APC/C) and may confer substrate specificity upon the complex. Is regulated by MAD2L1: in metaphase the MAD2L1-CDC20-APC/C ternary complex is inactive and in anaphase the CDC20-APC/C binary complex is active in degrading substrates. The CDC20-APC/C complex positively regulates the formation of synaptic vesicle clustering at active zone to the presynaptic membrane in postmitotic neurons. CDC20-APC/C-induced degradation of NEUROD2 induces presynaptic differentiation. Component of a complex with CDC20, CDC27, SPATC1 and TUBG1 (By similarity). Interacts with NEUROD2 (By similarity). Interacts with dimeric MAD2L1 in its closed conformation form (PubMed:9811605, PubMed:9637688, PubMed:15525512, PubMed:19098431, PubMed:29162720). Interacts with BUB1B (PubMed:15525512, PubMed:18997788, PubMed:19098431). The phosphorylated form interacts with APC/C (PubMed:9811605, PubMed:9734353, PubMed:9637688). Interacts with NINL (PubMed:17403670). May interact with MAD2L2 (PubMed:11459826). Interacts with CDK5RAP2 (PubMed:19282672). Interacts with SIRT2 (PubMed:22014574). Interacts with isoform 1 of NEK2 (PubMed:20034488). Interacts with HSF1 (via phosphorylated form); this interaction occurs in mitosis in a MAD2L1-dependent manner and prevents PLK1-stimulated degradation of HSF1 by blocking the recruitment of the SCF(BTRC) ubiquitin ligase complex (PubMed:18794143). Interacts (via the N-terminal substrate-binding domain) with FBXO5 (By similarity). Interacts with CCNF (PubMed:27653696).
