Comment typeDescription
Catalytic ActivityATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 4-phosphate.
FunctionThe phosphorylation of phosphatidylinositol (PI) to 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:0000250}.
SimilarityBelongs to the PI3/PI4-kinase family. Type II PI4K subfamily. {ECO:0000305}.
SimilarityContains 1 PI3K/PI4K domain. {ECO:0000305}.
SimilarityContains 2 ubiquitin-like domains. {ECO:0000255|PROSITE-ProRule:PRU00214}.
