CC -!- FUNCTION: E3 ubiquitin-protein ligase that mediates ubiquitination of
CC p53/TP53, leading to its degradation by the proteasome.
CC {ECO:0000250|UniProtKB:Q00987}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine +
CC [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-
CC cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine.;
CC EC=2.3.2.27; Evidence={ECO:0000250|UniProtKB:Q00987};
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm
CC {ECO:0000250|UniProtKB:P23804}. Cytoplasm
CC {ECO:0000250|UniProtKB:P23804}. Nucleus, nucleolus
CC {ECO:0000250|UniProtKB:P23804}. Nucleus {ECO:0000250|UniProtKB:Q00987}.
CC -!- DEVELOPMENTAL STAGE: Expression increases from oocyte stage I/II to
CC reach its maximum in oocyte stage v/vi in unfertilized eggs, and then
CC progressively decreases to become undetectable at the gastrula stage.
CC -!- SIMILARITY: Belongs to the MDM2/MDM4 family. {ECO:0000305}.
