May regulate MCM3AP phosphorylation through phosphatase recruitment (By similarity). May act as a negative regulator of ABCB1 expression and function through the dephosphorylation of ABCB1 by TFPI2/PPP2R3C complex . May play a role in the activation-induced cell death of B-cells (By similarity).
Subcellular locations: Nucleus, Cytoplasm
Excluded from the nucleoli. Localization is cell cycle-dependent. Localizes to the cytoplasm during cytokinesis.
Ubiquitously expressed in brain and other tissues.
