CC -!- FUNCTION: Acts on phosphatidylinositol (PtdIns) in the first committed
CC step in the production of the second messenger inositol-1,4,5,-
CC trisphosphate. {ECO:0000250|UniProtKB:P42356}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol) + ATP = a
CC 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol 4-phosphate) + ADP +
CC H(+); Xref=Rhea:RHEA:19877, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:57880, ChEBI:CHEBI:58178, ChEBI:CHEBI:456216;
CC EC=2.7.1.67; Evidence={ECO:0000250|UniProtKB:P42356};
CC -!- ACTIVITY REGULATION: Activated by Triton X-100, insensitive to
CC inhibition by adenosine and inhibited by wortmannin (By similarity).
CC The PI4K complex acts as a regulator of phosphatidylinositol 4-
CC phosphate (PtdIns(4)P) synthesis. Interaction with TMEM150A regulates
CC PtdIns(4)P synthesis (By similarity). {ECO:0000250|UniProtKB:O08662,
CC ECO:0000250|UniProtKB:P42356}.
CC -!- SUBUNIT: Component of a phosphatidylinositol 4-kinase (PI4K) complex,
CC composed of PI4KA, EFR3 (EFR3A or EFR3B), TTC7 (TTC7A or TTC7B) and
CC FAM126 (FAM126A or FAM126B). Interacts with TMEM150A; regulating
CC recruitment to the plasma membrane. Interacts with TTC7A.
CC {ECO:0000250|UniProtKB:P42356}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P42356}. Cell
CC membrane {ECO:0000250|UniProtKB:P42356}. Note=Localization to the
CC plasma membrane is mediated by the PI4K complex and association with
CC EFR3 (EFR3A or EFR3B), TTC7 (TTC7A or TTC7B) and FAM126 (FAM126A or
CC FAM126B). Localization to the plasma membrane is regulated by TMEM150A.
CC {ECO:0000250|UniProtKB:P42356}.
CC -!- DISRUPTION PHENOTYPE: Early embryonic lethality. Conditional knockout
CC mice show a dramatic depletion of cellular phosphatidylinositol 4-
CC phosphate (PtdIns(4)P). {ECO:0000269|PubMed:23229899}.
CC -!- SIMILARITY: Belongs to the PI3/PI4-kinase family. Type III PI4K
CC subfamily. {ECO:0000305}.
