Class III PI 3-kinase Class III PI 3-kinase is a subgroup of the enzyme family, phosphoinositide 3-kinase that share a common protein domain structure, substrate specificity and method of activation. There is only one known class III PI 3-kinase, Vps34, which is also the only PI 3-kinase expressed in all eukaryotic cells. In humans it is encoded by the PIK3C3 gene. In human cells Vps34 associates with a regulatory subunit, p150. ==Substrate specificity== Vps34 is more accurately described as a phosphatylinositol 3-kinase. ''In vivo'' Vps34 can phosphorylate only Phosphatidylinositol to form phosphatidylinositol (3)-phosphate (PtdIns(3)P).
