== Function Summary ==
* **Entrez Summary**: N/A
* **UniProt Summary**: Membrane-bound phosphatidylinositol-4 kinase (PI4- kinase) that catalyzes the phosphorylation of phosphatidylinositol (PI) to phosphatidylinositol 4-phosphate (PI4P), a lipid that plays important roles in endocytosis, Golgi function, protein sorting and membrane trafficking and is required for prolonged survival of neurons. 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}.
