  • Function

    Participates in the biosynthesis of phosphatidylinositol-4,5-bisphosphate. Mediates RAC1-dependent reorganization of actin filaments. Acts as an activator of TUT1 adenylyltransferase activity in nuclear speckles, thereby regulating mRNA polyadenylation of a select set of mRNAs. Contributes to the activation of PLD2.
  • Tissue specificity

    Highly expressed in heart, placenta, skeletal muscle, kidney and pancreas. Detected at lower levels in brain, lung and liver.
  • Sequence similarities

    Contains 1 PIPK domain.
  • Cellular localization

    Cell membrane. Endomembrane system. Golgi apparatus > Golgi stack. Nucleus speckle. Associated with the plasma membrane and with internal membranes. Associated with Golgi stacks (By similarity). Detected on RAC1-induced plasma membrane ruffles, and on membrane ruffles induced by platelet-derived growth factor. Localizes to nuclear speckles and associates with TUT1 to regulate polyadenylation of selected mRNAs.
