Lipid second messengers and related enzymes in vertebrate rod outer segments Giusto NM; Pasquare SJ; Salvador GA; Ilincheta de Boschero MGJ Lipid Res 2010[Apr]; 51 (4): 685-700Rod outer segments (ROSs) are specialized light-sensitive organelles in vertebrate photoreceptor cells. Lipids in ROS are of considerable importance, not only in providing an adequate environment for efficient phototransduction, but also in originating the second messengers involved in signal transduction. ROSs have the ability to adapt the sensitivity and speed of their responses to ever-changing conditions of ambient illumination. A major contributor to this adaptation is the light-driven translocation of key signaling proteins into and out of ROS. The present review shows how generation of the second lipid messengers from phosphatidylcholine, phosphatidic acid, and diacylglycerol is modulated by the different illumination states in the vertebrate retina. Findings suggest that the light-induced translocation of phototransduction proteins influences the enzymatic activities of phospholipase D, lipid phosphate phosphatase, diacylglyceride lipase, and diacylglyceride kinase, all of which are responsible for the generation of the second messenger molecules.|*Lipid Metabolism[MESH]|Animals[MESH]|Diglycerides/metabolism[MESH]|Humans[MESH]|Light Signal Transduction[MESH]|Lipids/*physiology[MESH]|Phosphatidic Acids/metabolism[MESH]|Phosphatidylcholines/metabolism[MESH]|Protein Transport[MESH]|Rod Cell Outer Segment/*enzymology/*metabolism[MESH]|Second Messenger Systems/*physiology[MESH] |
