| pubmed-article:2569501 | pubmed:abstractText | Crude as well as purified synaptic plasma membrane (SPM) preparations were analyzed for the influence of the ganglioside galactosyl-N-acetylgalactosaminyl-(N-acetylneuraminyl)-galactosylgluc osyl ceramide (GM1) on high-affinity binding of L-[3H]glutamate. Assayed in two different buffer systems, SPM consistently exhibited increased (40-50%) binding upon incubation with GM1 plus Ca2+, as compared to controls without GM1. Incorporation experiments with 3H-labeled GM1 proved trypsin-stable insertion of GM1 into SPM, with a maximum incorporation of four times the endogenous amount (35 nmol/mg of protein). The observed increase in glutamate binding was not due to a change in the affinity of the binding sites, but to a change in the number of binding sites, and it was absolutely dependent on the presence of Ca2+. A pharmacological profile of the GM1/Ca2+-stimulated glutamate binding is presented. The original classification of the stimulatory effect as an effect on glutamate receptor binding had to be revised to take into account the observed temperature sensitivity of the ganglioside effect, its sensitivity to high osmolarity and to ultrasonication, and the lack of binding stimulation after detergent treatment of membranes or after receptor solubilization. Vesicular space measured in both SPM preparations was found to be around 7 microliters/mg of protein, in ganglioside-treated as well as in control membranes. From the data, it is concluded that a special, Na+- and Cl- -independent form of glutamate transport into resealed membrane vesicles is stimulated by gangliosides in the presence of Ca2+. | lld:pubmed |
