WebDiacylglycerol and phosphatidic acid are two lipids that act as second messengers in signaling cascades. Their cellular concentrations are regulated by the encoded protein, and so it is thought to play an important role in cellular signal transduction. Alternative splicing results in two transcript variants encoding different isoforms. WebDiacylglycerol (DAG) is a glycerolipid with two fatty acyl chains attached to the central glycerol back bone [45]. It is also a potent second messenger signaling lipid often produced from the phospholipid phosphatidylinositol 4,5-bisphosphate by the enzyme phospholipase-C … on the basis of怎么读
