General annotation (Comments)

Function

Participates in the biosynthesis of phosphatidylinositol 4,5-bisphosphate. Mediates RAC1-dependent reorganization of actin filaments. Contributes to the activation of PLD2. Together with PIP5K1A is required after stimulation of G-protein coupled receptors for stable platelet adhesion. Ref.1 Ref.6 Ref.10

Catalytic activity

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

Enzyme regulation

Activated by phosphatidic acid. Ref.1 Ref.5

Subunit structure

Interacts with RAC1, AJUBA, PLD1, PLD2 and ARF1. Ref.6 Ref.7 Ref.8 Ref.9

Subcellular location

Endomembrane system By similarity. Note: Associated with membranes By similarity. Ref.7

Tissue specificity

Highly expressed in brain and testis. Barely detectable in liver and skeletal muscle. Ref.1

Sequence similarities

Contains 1 PIPK domain.

Caution

There is confusion in the literature with phosphatidylinositol 4-phosphate 5-kinase type I nomenclature due to the fact that frequently mouse PIP5K1B is named Phosphatidylinositol 4-phosphate 5-kinase type I alpha.
