CC -!- FUNCTION: May regulate MCM3AP phosphorylation through phosphatase
CC recruitment. May act as a negative regulator of ABCB1 expression and
CC function through the dephosphorylation of ABCB1 by TFPI2/PPP2R3C
CC complex. May play a role in the activation-induced cell death of B-
CC cells. {ECO:0000250|UniProtKB:Q969Q6, ECO:0000250|UniProtKB:Q9JK24}.
CC -!- SUBUNIT: Interacts with MCM3AP/GANP, PPP5C, and the phosphatase 2A core
CC enzyme composed of the PPP2CA catalytic subunit and the constant
CC regulatory subunit PPP2R1A. Finds in a complex with ABCB1, TFPI2 and
CC PPP2R3C; leading to the dephosphorylation of ABCB1.
CC {ECO:0000250|UniProtKB:Q969Q6, ECO:0000250|UniProtKB:Q9JK24}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9JK24}. Cytoplasm
CC {ECO:0000250|UniProtKB:Q9JK24}. Note=Excluded from the nucleoli.
CC Localization is cell cycle-dependent. Localizes to the cytoplasm during
CC cytokinesis. {ECO:0000250|UniProtKB:Q9JK24}.
