phospholipid transfer activity phosphatidic acid transfer activity rb GO:1990050 phosphatidic acid carrier activity intermembrane phosphatidic acid transfer activity molecular_function phosphatidic acid transporter activity intermembrane PA transfer activity Removes a phosphatidic acid from a membrane or a monolayer lipid particle, transports it through the aqueous phase while protected in a hydrophobic pocket, and brings it to an acceptor membrane or lipid particle. Phosphatidic acid refers to a glycophospholipids with, in general, a saturated fatty acid bonded to carbon-1, an unsaturated fatty acid bonded to carbon-2, and a phosphate group bonded to carbon-3. 2013-02-21T00:45:28Z
