Protein attributes

Sequence length	742 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved, together with the calcineurin ppb1, in cytokinesis. Ref.1
Catalytic activity	ATP + 1-phosphatidyl-1D-myo-inositol 4-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate.
Subcellular location	Nucleus. Membrane; Peripheral membrane protein. Note: The active form of the enzyme is membrane-associated and concentrates at the septum in dividing cells. Ref.1 Ref.3 Ref.4
Post-translational modification	Phosphorylated by casein kinase I. Phosphorylation inactivates the enzyme. Ref.4
Sequence similarities	Contains 1 PIPK domain.
