CC -!- FUNCTION: Catalyzes the covalent attachment of ubiquitin to other
CC proteins. Acts as an essential factor of the anaphase promoting
CC complex/cyclosome (APC/C), a cell cycle-regulated ubiquitin ligase that
CC controls progression through mitosis. Acts by specifically elongating
CC polyubiquitin chains initiated by the E2 enzyme ubch10 on APC/C
CC substrates, enhancing the degradation of APC/C substrates by the
CC proteasome and promoting mitotic exit. {ECO:0000255|PROSITE-
CC ProRule:PRU00388}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E1 ubiquitin-activating enzyme]-L-cysteine +
CC [E2 ubiquitin-conjugating enzyme]-L-cysteine = [E1 ubiquitin-
CC activating enzyme]-L-cysteine + S-ubiquitinyl-[E2 ubiquitin-
CC conjugating enzyme]-L-cysteine.; EC=2.3.2.23;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00388, ECO:0000255|PROSITE-
CC ProRule:PRU10133};
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
CC -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
