Unitary EPSC histograms with multiple peaks were fitted satisfactorily under the assumption that quantal events have a slightly skewed amplitude distribution and that the release mechanism is described by models with either binomial (standard), nonuniform, or nonstationary statistics. The average peak current of the quantal event derived from these fits reflected the opening of between 15 and 65 glutamate receptor (GluR) channels of the AMPAR subtype. The variability in the amplitude of quantal events is characterized by a CVq of 25% to 30%. The best fits to multiple peak EPSC histograms are obtained if it is assumed that the number of release sites contained within a single MF-bouton is between 8 and 21, a value comparable to the published number of morphologically measured presynpatic active zones and postsynaptic densities (PSDs) of individual MF-CA3 synapses. This suggests that at the MF-CA3 synapse each presynaptic zone and its associated PSD act as independent units, contributing one quantal event to unitary EPSCs. Simulations of unitary EPSC distributions, based on measurements of PSD size could, however, indicate that the interpretation of multipeak EPSC amplitude distributions at MF-CA3 synapses in terms of fluctuating release probabilities might be an over-simplification, and that postsynaptic factors may contribute significantly to fluctuations of unitary EPSC amplitudes.</p>","PeriodicalId":76981,"journal":{"name":"Advances in second messenger and phosphoprotein research","volume":"29 ","pages":"235-60"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18848291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use an affinity purification scheme, based on the function of SNAP receptor in assembling 20S fusion particles from NSF and SNAP proteins, to purify SNAP receptors from brain. Remarkably, each of the four SNAP receptors (or, SNAREs) thus delineated resides in synapses, with one receptor originating in the synaptic vesicle and another in the presynaptic plasma membrane that is targeted for fusion. This suggests a simple mechanism in which the general NSF/SNAP fusion machinery can assemble to bridge partner membranes in a complex containing elements of both vesicle and target membranes, and implies that similar fusion machines drive both constitutive fusion (ER-->Golgi-->surface and endocytosis) and regulated exocytosis. The vesicle (v-SNARE) and the target-associated t-SNAREs from the synapse are each members of compartmentally-specific families of membrane proteins found in yeast, animal cells, and neurons, thus raising the possibility that v-SNAREs and t-SNAREs encode specificity in membrane fusion processes that utilize a common mechanism.</p>","PeriodicalId":76981,"journal":{"name":"Advances in second messenger and phosphoprotein research","volume":"29 ","pages":"81-96"},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18848254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
