pfam17256: ANAPC16 (This model is not part of the current CDD release)
Anaphase-promoting complex, subunit 16
The Anaphase-promoting complex/cyclosome (APC/C) is a 1.5 megaDaltons assembly ubiquitin ligase complex comprising 19 subunits. This multifunctional ubiquitin-protein ligase targets different substrates for ubiquitylation and therefore regulates a variety of cellular processes such as cell division, differentiation, genome stability, energy metabolism, cell death, autophagy as well as carcinogenesis. The APC/C complex contains two sub-complexes,the Platform and the Arc Lamp. The Arc Lamp, which mediates transient association with regulators and ubiquitination substrates, contains the small subunits APC16, CDC26, APC13, and tetratricopeptide repeat (TPR) proteins. APC16 is a conserved subunit of the APC/C. APC16 was found in association with tandem-affinity-purified mitotic checkpoint complex protein complexes. APC16 is a bona fide subunit of human APC/C. It is present in APC/C complexes throughout the cell cycle. The phenotype of APC16-depleted cells copies depletion of other APC/C subunits, and APC16 is important for APC/C activity towards mitotic substrates. APC16 sequence homologues can be identified in metazoans, but not fungi, by four conserved primary sequence stretches.
