CC -!- FUNCTION: The ube2v/ube2n heterodimer catalyzes the synthesis of non-
CC canonical poly-ubiquitin chains that are linked through 'Lys-63'. This
CC type of poly-ubiquitination does not lead to protein degradation by the
CC proteasome. Mediates transcriptional activation of target genes. Plays
CC a role in the control of progress through the cell cycle and
CC differentiation. Plays a role in the error-free DNA repair pathway and
CC contributes to the survival of cells after DNA damage.
CC {ECO:0000250|UniProtKB:P61088}.
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 -!- SUBUNIT: Heterodimer with ube2v. {ECO:0000250|UniProtKB:P61088}.
CC -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
CC {ECO:0000255|PROSITE-ProRule:PRU00388}.
