Plasma membranes lipids

As noted above, synaptic vesicles are not typically generated at the level of the TGN. Instead, they are assembled from endocytosed material retrieved from the synaptic plasma membrane. Synaptic vesicle and plasma membrane lipids and proteins are synthesized in the endoplasmic reticulum and modified in the Golgi apparatus, where they are then packaged in secretory vesicles. These synaptic precursors are delivered to the plasma membrane from the cell body by the constitutive secretory pathway. Synaptic vesicle proteins must be retrieved by clathrin-mediated synaptic vesicle endocytosis, a variant of RME with some neuron-specific components. Once the vesicle sheds its clathrin coat, the uncoated vesicle fuses with a...

Plasma membrane lipids are asymmetrically distributed between the two monolayers of the bilayer, although the asymmetry, unlike that of membrane proteins, is not absolute. In the plasma membrane of the erythrocyte, for example, choline-containing lipids (phosphatidylcholine and sphingomyelin) are typically found in the outer (extracellular or exoplasmic) leaflet (Fig. 11-5), whereas phosphatidylserine, phosphatidyl-ethanolamine, and the phosphatidylinositols are much more common in the inner (cytoplasmic) leaflet. Changes in the distribution of lipids between plasma membrane leaflets have biological consequences. For example, only when the phosphatidylserine in the plasma membrane moves into the outer leaflet is a platelet able to play its role in formation of a blood clot. For many other cells types, phosphatidylserine exposure on the outer surface marks a cell for destruction by programmed cell death. 

A second class of serpentine receptors are coupled through a G protein to a plasma membrane phospholipase C (PLC) that is specific for the plasma membrane lipid phosphatidylinositol 4,5-bisphosphate (see Fig. 10-15). This hormone-sensitive enzyme catalyzes the formation of two potent second messengers diacyl-glycerol and inositol 1,4,5-trisphosphate, or IP i (not to be confused with PIP3, p. 431).

Another open issue in GPI hydrolysis by phospholipases is how intracellular receptor activation couples to the hydrolysis of an extracellular plasma membrane lipid. There are many hypotheses that have not been fully explored, some of which have an experimental basis - for example, there are evidences of fhe presence of both free-GPI and GPI-PLD in intracellular vesicles [27, 30]. Alfhough intracellular GPI-PLD has not been reported to hydrolyse GPI, an intracellular re-...

There is a scarcity of data for the analyses of glyoxysomal membranes and plasma membranes of plant cells. The glyoxysomal membrane from castor bean (Ricinus communis L.) endosperm has PC as the major lipid together with PE, 80% of the phospholipid can be accounted for. Plasma membranes isolated from oat Avena saliva L.) roots showed relatively lai ge amounts of phosphatidic acid (PA), (1,2-diacyl-jn-glycerol 3-phosphate) and an unknown lipid (Keenan et al., 1973). It is possible that some lipid degradation took place in the preparation of this sample. Further analyses of the lipid composition would be most appropriate. The analyses of Keenan et al. (1973) indicated that only 28.6% of the plasma membrane lipid was phospho-...
