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       'Lys-11'-linked polyubiquitin chains initiated by the E2 enzyme
CC       ube2c/ubch10 on APC/C substrates, enhancing the degradation of APC/C
CC       substrates by the proteasome and promoting mitotic exit.
CC       {ECO:0000255|PROSITE-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}.
