Protein attributes

Sequence length	394 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at transcript level.

General annotation (Comments)

Function	May act as a scaffold to localize and regulate type I PI4P 5-kinases to specific compartments within the cell, where they generate PI(4,5)P2 for actin nucleation, signaling and scaffold protein recruitment and conversion to PI(3,4,5)P3 By similarity.
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate.
Subunit structure	Heterodimerizes with other type I phosphatidylinositol-4-phosphate 5-kinase By similarity.
Subcellular location	Cytoplasm. Membrane. Note: Localized to large cytoplasmic vesicular structures By similarity.
Sequence similarities	Contains 1 PIPK domain.
Caution	It is unsure if the enzyme has intrinsic kinase activity.
