Overview
INPP4B Catalyzes the hydrolysis of the 4-position phosphate of phosphatidylinositol 3,4-bisphosphate, inositol 1,3,4- trisphosphate and inositol 1,4-bisphosphate. Widely expressed with highest levels occurring in the skeletal muscle and heart. Strongly inhibited by inositol hexakisphosphate. Belongs to the inositol 3,4-bisphosphate 4-phosphatase family. Note: This description may include information from UniProtKB.
Protein type: EC 3.1.3.66; Phosphatase, lipid; Motility/polarity/chemotaxis; Carbohydrate Metabolism - inositol phosphate
Cellular Component: Golgi apparatus; cytosol
Molecular Function: phosphatidylinositol-3,4-bisphosphate 4-phosphatase activity; lipid binding
Biological Process: cellular calcium ion homeostasis; negative regulation of osteoclast differentiation; inositol phosphate metabolic process; regulation of nucleocytoplasmic transport; phospholipid metabolic process; phosphatidylinositol biosynthetic process; regulation of bone remodeling; regulation of protein kinase B signaling cascade; signal transduction
