WebMar 1, 2013 · PAP activity controls the expression of PSS for membrane phospholipid synthesis, and shows that Cho1 expression in the pah1Δ mutant is induced through the inositol-sensitive upstream activation sequence, a cis-acting element for the phosphatidate-controlled Henry (Ino2–Ino4/Opi1) regulatory circuit. 32 PDF Phosphatidate phosphatase regulates lipid metabolism in several ways. In short, it is a key player in controlling the overall flux of triacylglycerols to phospholipids and vice versa, also exerting control through the generation and degradation of lipid-signaling molecules related to phosphatidate. When the phosphatase is … See more The enzyme phosphatidate phosphatase (PAP, EC 3.1.3.4) is a key regulatory enzyme in lipid metabolism, catalyzing the conversion of phosphatidate to diacylglycerol: a 1,2-diacylglycerol … See more PAP belongs to the family of enzymes known as hydrolases, and more specifically to the hydrolases that act on phosphoric See more There are several different genes that code for phosphatidate phosphatases. They fall into one of two types (type I and type II), depending on their cellular localization and … See more Human genes that encode phosphatidate phosphatases include: • PPAP2A (LPP1) – phosphatidic acid phosphatase type 2A • PPAP2B (LPP3) – phosphatidic acid phosphatase type 2B • PPAP2C (LPP2) – phosphatidic acid phosphatase type 2C See more Phosphatidate phosphatase is up-regulated by CDP-diacylglycerol, phosphatidylinositol (formed from reaction of CDP-diacylglycerol with inositol), and cardiolipin. It is down-regulated by sphingosine and dihydrosphingosine. This makes sense in the … See more The systematic name is diacylglycerol-3-phosphate phosphohydrolase.
