OAG is a cell-permeable analog of the PKC-activating second messenger DAG. It activates PKC in platelets, resulting in the phosphorylation of a 40 kDa protein.{656} OAG is metabolized to its corresponding phosphatidic acid (1-oleoyl-2-acetyl-3-phosphoglycerol), most likely through the action of a diglycerol kinase.{656}
