Protein
Ubiquitin-conjugating enzyme E2 S
Organism
Branchiostoma floridae
Function
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 controls progression through mitosis. Acts by specifically elongating polyubiquitin chains initiated by the E2 enzyme UBCH10 on APC/C substrates, enhancing the degradation of APC/C substrates by the proteasome and promoting mitotic exit.
Similarity
Belongs to the ubiquitin-conjugating enzyme family.
