CC -!- FUNCTION: Phosphorylates phosphatidylinositol (PI) in the first
CC committed step in the production of the second messenger inositol-
CC 1,4,5,-trisphosphate (PIP). May regulate Golgi
CC disintegration/reorganization during mitosis, possibly via its
CC phosphorylation (By similarity). Involved in Golgi-to-plasma membrane
CC trafficking (By similarity). {ECO:0000250|UniProtKB:O08561,
CC ECO:0000250|UniProtKB:Q9UBF8}.
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 ChEBI:CHEBI:57880, ChEBI:CHEBI:58178, ChEBI:CHEBI:456216;
CC EC=2.7.1.67; Evidence={ECO:0000250|UniProtKB:Q9UBF8};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:19878;
CC Evidence={ECO:0000250|UniProtKB:Q9UBF8};
CC -!- COFACTOR:

CC Evidence={ECO:0000250|UniProtKB:Q9UBF8};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:Q9UBF8};
CC -!- ACTIVITY REGULATION: Inhibited by wortmannin. Increased kinase activity
CC upon interaction with NCS1/FREQ. {ECO:0000250|UniProtKB:O02810}.
CC -!- SUBUNIT: Interacts with ARF1 and ARF3 in the Golgi complex, but not
CC with ARF4, ARF5 or ARF6 (By similarity). Interacts with NCS1/FREQ in a
CC calcium-independent manner. Interacts with CALN1/CABP8 and CALN2/CABP7;
CC in a calcium-dependent manner; this interaction competes with NCS1/FREQ
CC binding (By similarity). Interacts with ACBD3. Interacts with ARMH3,
CC YWHAB, YWHAE, YWHAG, YWHAH, YWHAQ, YWHAZ and SFN (By similarity).
CC Interacts with GGA2 (via VHS domain); the interaction is important for
CC PI4KB location at the Golgi apparatus membrane (By similarity).
CC Interacts with ATG9A. {ECO:0000250|UniProtKB:O08561,
CC ECO:0000250|UniProtKB:Q9UBF8}.
CC -!- SUBCELLULAR LOCATION: Endomembrane system {ECO:0000250}. Mitochondrion
CC outer membrane {ECO:0000250}; Peripheral membrane protein
CC {ECO:0000250}. Rough endoplasmic reticulum membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}. Golgi apparatus
CC {ECO:0000250}. Golgi apparatus membrane {ECO:0000250|UniProtKB:Q9UBF8}.
CC Note=Found in the outer membrane of mitochondria and membranes of the
CC rough endoplasmic reticulum. Recruited to the Golgi complex by the
CC small GTPase ARF to stimulate the synthesis of phosphatidylinositol
CC 4,5-bisphosphate (PIP2) on the Golgi complex. Recruited to the Golgi
CC apparatus membrane by ACBD3, GGA2 is also involved in the recruitment
CC (By similarity). {ECO:0000250|UniProtKB:Q9UBF8}.

CC Name=3;
CC IsoId=Q8BKC8-3; Sequence=VSP_037134;
CC -!- SIMILARITY: Belongs to the PI3/PI4-kinase family. Type III PI4K
CC subfamily. {ECO:0000305}.
