Putative tyrosine-protein phosphatase TPTE is an enzyme that in humans is encoded by the TPTE gene.[1][2]

Function[edit]

TPTE is a member of a large class of membrane-associated phosphatases with substrate specificity for the 3-position phosphate of inositol phospholipids.[2] TPTE is believed to lack phosphatase activity; however, the closely related protein TPIP, also called TPTE2 is an active phosphatase with activity against inositol phospholipid substrates.[3] TPTE and TPIP are the mammalian homologues to the family of voltage sensitive phosphatases.
