INPP1

Inositol polyphosphate 1-phosphatase is an enzyme that, in humans, is encoded by the INPP1 gene.^[5][6] INPP1 encodes the enzyme inositol polyphosphate-1-phosphatase, one of the enzymes involved in phosphatidylinositol signaling pathways. This enzyme removes the phosphate group at position 1 of the inositol ring from the polyphosphates inositol 1,4-bisphosphate and inositol 1,3,4-trisphophosphate.^[6]
