CC -!- FUNCTION: Has E3 ubiquitin ligase activity towards IGBP1, promoting its
CC monoubiquitination, which results in deprotection of the catalytic
CC subunit of protein phosphatase PP2A, and its subsequent degradation by
CC polyubiquitination. {ECO:0000250|UniProtKB:O15344}.
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: Homodimer or heterodimer with MID2. Interacts with IGBP1.
CC {ECO:0000250|UniProtKB:O15344}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:O15344}.
CC Cytoplasm, cytoskeleton {ECO:0000250|UniProtKB:O15344}.
CC Note=Microtubule-associated. {ECO:0000250|UniProtKB:O15344}.
CC -!- SIMILARITY: Belongs to the TRIM/RBCC family. {ECO:0000305}.
