Ubiquitin-conjugating enzyme E2 C

UniProtKB accession:  Q95044

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the covalent attachment of ubiquitin to other proteins. Acts as an essential factor of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated ubiquitin ligase that is essential for the transition from metaphase to anaphase in mitosis. Involved in both degradation of proteins responsible for maintaining sister chromatid cohesion at the onset of anaphase and of mitotic cyclins A and B at the exit of mitosis. Acts by initiating polyubiquitin chains on APC/C substrates, leading to the degradation of APC/C substrates by the proteasome and promoting mitotic exit.
