Function: Catalyzes the phosphorylation of phosphatidylinositol 4-phosphate (PtdIns4P) to form phosphatidylinositol 4, 5-bisphosphate (PtdIns(4, 5)P2). PtdIns(4, 5)P2 is involved in a variety of cellular processes and is the substrate to form phosphatidylinositol 3, 4, 5-trisphosphate (PtdIns(3, 4, 5)P3), another second messenger. The majority of PtdIns(4, 5)P2 is thought to occur via type I phosphatidylinositol 4-phosphate 5-kinases given the abundance of PtdIns4P. Participates in a variety of cellular processes such as vesicle mediated transport, cell adhesion, cell polarization and cell migration. Together with PIP5K1A is required for phagocytosis, but they regulate different types of actin remodeling at sequential steps. Promotes particle attachment by generating the pool of PtdIns(4, 5)P2 that induces controlled actin depolymerization to facilitate Fc-gamma-R clustering. Mediates RAC1-dependent reorganization of actin filaments. Required for synaptic vesicle transport. Controls the plasma membrane pool of PtdIns(4, 5)P2 implicated in synaptic vesicle endocytosis and exocytosis. Plays a role in endocytosis mediated by clathrin and AP-2 (adaptor protein complex 2). Required for clathrin-coated pits assembly at the synapse. Participates in cell junction assembly. Modulates adherens junctions formation by facilitating CDH1 trafficking. Required for focal adhesion dynamics. Modulates the targeting of talins (TLN1 and TLN2) to the plasma membrane and their efficient assembly into focal adhesions. Regulates the interaction between talins (TLN1 and TLN2) and beta-integrins. Required for uropodium formation and retraction of the cell rear during directed migration. Has a role in growth factor-stimulated directional cell migration and adhesion. Required for talin assembly into nascent adhesions forming at the leading edge toward the direction of the growth factor. Negative regulator of T-cell activation and adhesion. Negatively regulates integrin alpha-L/beta-2 (LFA-1) polarization and adhesion induced by T-cell receptor. Together with PIP5K1A has a role during embryogenesis and together with PIP5K1B may have a role immediately after birth.
Subunit Structure: Interacts with TLN1 (By similarity). Interacts with TLN2; interaction stimulates lipid kinase activity. May compete with beta-integrins for the same on TLN1 and TLN2. Interacts with ARF6. Interacts with AP2B1. Interacts with AP2M1; phosphorylation of PIP5K1C by CSK disrupts the interaction; clathrin competes with PIP5K1C (By similarity). Interacts with CDH1. Interacts with CSK (By similarity). Interacts with PLCG1; interaction is abolished upon EGF stimulation (By similarity). Interacts with LAPTM4B; promotes SNX5 association with LAPTM4B; kinase activity of PIP5K1C is required; interaction is regulated by phosphatidylinositol 4, 5-bisphosphate generated by PIP5K1C (PubMed:25588945).
Post-translational Modifications: Phosphorylation on Ser-650 negatively regulates binding to TLN2 and is strongly stimulated in mitosis. Phosphorylation on Tyr-649 is necessary for targeting to focal adhesions. Phosphorylation on Ser-650 and Tyr-649 are mutually exclusive. Phosphorylated by SYK and CSK (By similarity). Tyrosine phosphorylation is enhanced by PTK2 signaling. Phosphorylated at Tyr-639 upon EGF stimulation. Some studies suggest that phosphorylation on Tyr-649 enhances binding to tailins (TLN1 and TLN2). According to PubMed:15738269 phosphorylation at Tyr-649 does not directly enhance binding to tailins (TLN1 and TLN2) but may act indirectly by inhibiting phosphorylation at Ser-650. Acetylation at Lys-265 and Lys-268 seems to decrease lipid kinase activity. Deacetylation of these sites by SIRT1 positively regulates the exocytosis of TSH-containing granules from pituitary cells.

This locus encodes a type I phosphatidylinositol 4-phosphate 5-kinase. The encoded protein catalyzes phosphorylation of phosphatidylinositol 4-phosphate, producing phosphatidylinositol 4,5-bisphosphate. This enzyme is found at synapses and has been found to play roles in endocytosis and cell migration. Mutations at this locus have been associated with lethal congenital contractural syndrome. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Sep 2010]
