Protein attributes

Sequence length	479 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	Contributes to the overall PI4-kinase activity of the cell. The 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) By similarity.
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 4-phosphate.
Subcellular location	Cytoplasm By similarity. Membrane By similarity.
Sequence similarities	Belongs to the PI3/PI4-kinase family. Type II PI4K subfamily. Contains 1 PI3K/PI4K domain.
