Sequence statusComplete.
Protein existenceEvidence at protein level

General annotation (Comments)

Function

Participates in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. Ref.1

Catalytic activity

ATP + 1-phosphatidyl-1D-myo-inositol 5-phosphate = ADP + 1-phosphatidyl-1D-myo-inositol 4,5-bisphosphate.

Subunit structure

Homodimer. Binds TNFRSF1A. Interacts with PIP4K2A. Interaction with PIP4K2A suppresses ubiquitination by the SPOP/ CUL3 complex By similarity.

Subcellular location

Endoplasmic reticulum membrane; Peripheral membrane protein By similarity. Cell membrane; Peripheral membrane protein By similarity. Nucleus By similarity. Cytoplasm By similarity. Note: Associated with the plasma membrane and the endoplasmic reticulum By similarity. Ref.1

Post-translational modification

Phosphorylated on serine residues. Ubiquitinated by the SPOP/CUL3 complex. Ubiquitination is stimulated by PtdIns5P levels By similarity. Ref.1

Sequence similarities

Contains 1 PIPK domain.
