APC/C activator protein CDH1

UniProtKB accession:  P53197

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Activator protein that regulates the ubiquitin ligase activity and substrate specificity of the anaphase promoting complex/cyclosome (APC/C). During telophase and in the subsequent G1 phase of the cell cycle, recognizes and binds proteins containing a destruction box (D-box) and an additional degradation signal termed the KEN box including ASE1, CDC20, the B-type cyclins CLB2 and CLB3, the polo-like kinase CDC5 and HSL1, and recruits them in a C-box-dependent manner to the APC/C for ubiquitination and subsequent proteolysis. Required for exit from mitosis, cytokinesis and formation of prereplicative complexes in G1. Probably is the target of a BUB2-dependent spindle checkpoint pathway.
