CC -!- FUNCTION: RNA-binding protein. May be involved in post-transcriptional
CC regulatory mechanisms, modulating levels of some mRNAs by promoting
CC their degradation in a way involving ubiquitin ligase activity. May act
CC as suppressor of replication stress and chromosome missegregation.
CC {ECO:0000250}.
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;
CC -!- SUBUNIT: Interacts with USP7, which antagonizes the ability to degrade
CC mRNA. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Note=Predominantly expressed in the cytoplasm and shuttles between the
CC cytoplasm and the nucleus through the CRM1 export pathway.
CC -!- DOMAIN: Binds RNA through its KH domains. {ECO:0000250}.
CC -!- PTM: Phosphorylated. {ECO:0000250}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAI25428.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
