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]. * **UniProt Summary**: 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. {ECO:0000269|PubMed:12422219, ECO:0000269|PubMed:12847086, ECO:0000269|PubMed:17261850, ECO:0000269|PubMed:17635937}. |PIP5K| |1-phosphatidylinositol-4-phosphate 5-kinase activity| |uropod| |clathrin-dependent endocytosis| |phagocytic cup| |adherens junction assembly| |synaptic vesicle endocytosis| |presynaptic endocytosis| |phosphatidylinositol phosphorylation| |synaptic vesicle recycling| |synaptic vesicle exocytosis| |lipid phosphorylation| |neutrophil chemotaxis| |adherens junction organization| |granulocyte chemotaxis| |neutrophil migration| |presynapse| |ruffle membrane| |granulocyte migration| |signal release from synapse| |neurotransmitter secretion| |phosphatidylinositol biosynthetic process| |synaptic vesicle cycle| |regulation of phosphatidylinositol 3-kinase signaling| |myeloid leukocyte migration| |vesicle-mediated transport in synapse| |leukocyte chemotaxis| |phosphatidylinositol metabolic process| |cell junction assembly| |signal release| |neurotransmitter transport| |lipid modification| |glycerophospholipid biosynthetic process| |cell chemotaxis| |endosome membrane| |cell junction organization| |glycerolipid biosynthetic process| |receptor-mediated endocytosis| |phospholipid biosynthetic process| |glycerophospholipid metabolic process| |phagocytosis| |regulation of neurotransmitter levels| |phospholipid metabolic process| |leukocyte migration| |glycerolipid metabolic process| |focal adhesion| |chemical synaptic transmission| |anterograde trans-synaptic signaling| |trans-synaptic signaling| |synaptic signaling| |actin cytoskeleton organization| |cell-cell adhesion| |organophosphate biosynthetic process| |chemotaxis| |taxis| |endocytosis| |actin filament-based process| |lipid biosynthetic process| |import into cell| |regulated exocytosis| |exocytosis| |membrane organization| |organophosphate metabolic process| |cell adhesion| |biological adhesion| |cellular lipid metabolic process| |cell migration| |secretion by cell| |export from cell| |cell motility| |localization of cell| |cytoskeleton organization| |cell-cell signaling| |secretion| |lipid metabolic process| |phosphorylation| |locomotion| |ATP binding| |movement of cell or subcellular component| |regulation of intracellular signal transduction| |establishment of localization in cell| |vesicle-mediated transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp11|CCCP 1μM R00 exp11]]|-1.98| |[[:results:exp17|DABN 20μM R00 exp17]]|-1.75| |[[:results:exp359|FK-506 30μM R07 exp359]]|1.73| ^Gene^Correlation^ |[[:human genes:r:rrm1|RRM1]]|0.503| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 6110 * **Expression level (log2 read counts)**: 4.03 {{:chemogenomics:nalm6 dist.png?nolink |}}
