PIP5K1B Participates in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. Mediates RAC1-dependent reorganization of actin filaments. Contributes to the activation of PLD2. Together with PIP5K1A is required after stimulation of G-protein coupled receptors for stable platelet adhesion. Detected in heart, pancreas, brain, kidney, skeletal muscle and lung. 3 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
