Besides, phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P) is the first committed step in the generation of phosphatidylinositol 4,5-bisphosphate (PIP2), a precursor of the second messenger inositol 1,4,5-trisphosphate (InsP3). {ECO:0000269|PubMed:11279162, ECO:0000269|PubMed:16443754, ECO:0000269|PubMed:20388919, ECO:0000269|PubMed:23146885, ECO:0000269|PubMed:24675427, ECO:0000269|PubMed:25168678, ECO:0000305}. |PI3 PI4 kinase| |growing cell tip| |host cell presynaptic membrane| |AP-3 adaptor complex binding| |1-phosphatidylinositol 4-kinase activity| |intrinsic component of membrane| |BLOC-1 complex| |phosphatidylinositol phosphorylation| |lipid phosphorylation| |presynaptic membrane| |endosome organization| |phosphatidylinositol biosynthetic process| |Golgi organization| |phosphatidylinositol metabolic process| |trans-Golgi network| |lipid modification| |glycerophospholipid biosynthetic process| |magnesium ion binding| |glycerolipid biosynthetic process| |membrane raft| |phospholipid biosynthetic process| |cytoplasmic vesicle| |endosome| |vesicle organization| |lysosomal membrane| |glycerophospholipid metabolic process| |neuron projection| |neuronal cell body| |phospholipid metabolic process| |glycerolipid metabolic process| |endomembrane system organization| |dendrite| |organophosphate biosynthetic process| |cell junction| |lipid biosynthetic process| |organophosphate metabolic process| |cellular lipid metabolic process| |lipid metabolic process| |mitochondrion| |phosphorylation| |integral component of plasma membrane| |ATP binding| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp434|Vemurafenib 6.6μM R08 exp434]]|-2.71| No correlation found to any other genes in chemogenomics.
