Function

TPTE is a member of a large class of membrane-associated phosphatases with substrate specificity for the 3-position phosphate of inositol phospholipids.^[4] TPTE is a primate-specific duplicate of the TPTE2 (TPIP) inositol phospholipid phosphatase;^[5] TPTE itself is predicted to lack phosphatase activity.^[6] TPTE and TPTE2 are the mammalian homologues to the subfamily of voltage sensitive phosphatases.
