Function Bifunctional inositol kinase that acts in concert with the IP6K kinases IP6K1, IP6K2 and IP6K3 to synthesize the diphosphate group-containing inositol pyrophosphates diphosphoinositol pentakisphosphate, PP-InsP5, and bis- diphosphoinositol tetrakisphosphate, (PP)2-InsP4. PP-InsP5 and (PP)2-InsP4, also respectively called InsP7 and InsP8, regulate a variety of cellular processes, including apoptosis, vesicle trafficking, cytoskeletal dynamics, exocytosis, insulin signaling and neutrophil activation. Phosphorylates inositol hexakisphosphate (InsP6) at positions 1 or 3 to produce PP-InsP5 which is in turn phosphorylated by IP6Ks to produce (PP)2-InsP4. Alternatively, phosphorylates at position 1 or 3 PP-InsP5, produced by IP6Ks from InsP6, to produce (PP)2-InsP4. Activated when cells are exposed to hyperosmotic stress. {ECO:0000269|PubMed:17412958, ECO:0000269|PubMed:17690096, ECO:0000269|PubMed:17702752}.
Subcellular Location Cytoplasm, cytosol. Cell membrane. Note=Relocalizes to the plasma membrane upon activation of the PtdIns 3-kinase pathway.
Tissue Specificity Widely expressed, with a higher expression in skeletal muscle, heart and brain. {ECO:0000269|PubMed:17690096}.
