General annotation (Comments)

Function	Acts on phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol-1,4,5,-trisphosphate. STT4 functions in PKC1 protein kinase pathway.
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol = ADP + 1-phosphatidyl-1D-myo-inositol 4-phosphate.
Miscellaneous	Present with 846 molecules/cell in log phase SD medium. Ref.3
Sequence similarities	Belongs to the PI3/PI4-kinase family. Type III PI4K subfamily. Contains 1 PI3K/PI4K domain.
