Recent evidence suggests that Snapin may be an important intermediate in this process, through simultaneous interactions of Snapin dimers with SNAP-25 and Synaptotagmin. In support of this model, cultured neurons derived from embryonically lethal Snapin null mutant mice exhibit desynchronized release and a reduced readily releasable vesicle pool. Based on evidence that a dimerization-defective Snapin mutation specifically disrupts priming, Snapin is hypothesized to stabilize primed vesicles by structurally coupling Synaptotagmin and SNAP-25. To explore this model in vivo we examined synaptic transmission in viable, adult C. elegans Snapin (snpn-1) mutants. The kinetics of synaptic transmission were unaffected at snpn-1 mutant neuromuscular junctions (NMJs), but the number of docked, fusion competent vesicles was significantly reduced. However, analyses of snt-1 and snt-1;snpn-1 double mutants suggest that the docking role of SNPN-1 is independent of Synaptotagmin. Based on these results we propose that the primary role of Snapin in C. elegans is to promote vesicle priming, consistent with the stabilization of SNARE complex formation through established interactions with SNAP-25 upstream of the actions of Synaptotagmin in calcium-sensing and endocytosis.","is_dataset_classified":null,"base_score":3.2188758248682006,"endowment":3.2188758248682006,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"23469084","pmcid":"PMC3585204","openalex_id":"https://openalex.org/W1984502589","authors":[],"funders":[{"funder_name":"NIH HHS","grant_id":"P40 OD010440","title":null},{"funder_name":"NIMH NIH HHS","grant_id":"R01 MH073156-03","title":null},{"funder_name":"NIMH NIH HHS","grant_id":"R01 MH073156","title":null},{"funder_name":"National Institutes of Health","grant_id":"1R01MH073156-01A2","title":"The role of tomosyn in synaptic transmission."},{"funder_name":"National Institutes of Health","grant_id":"1P40OD010440-01","title":"Caenorhabditis Genetics Center"}],"total_grants":5,"fwci":1.0649,"citation_percentile":0.7330899,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2014,"count":2},{"year":2015,"count":3},{"year":2016,"count":1},{"year":2017,"count":2},{"year":2018,"count":2},{"year":2020,"count":1},{"year":2021,"count":3},{"year":2022,"count":1},{"year":2023,"count":4},{"year":2024,"count":3},{"year":2025,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0057842&type=printable","host_type":"journal"},{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0057842&type=printable","host_type":"publisher"},{"url":"http://dx.plos.org/10.1371/journal.pone.0057842","host_type":"publisher"},{"url":"https://doi.org/10.1371/journal.pone.0057842","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/23469084","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/3585204","host_type":"repository"},{"url":"https://doaj.org/article/b7cc8fc0defb405191019fb162d1e06c","host_type":"repository"},{"url":"https://figshare.com/articles/journal_contribution/Differential_Roles_for_Snapin_and_Synaptotagmin_in_the_Synaptic_Vesicle_Cycle/10770995","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC3585204","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC3585204?pdf=render","host_type":"Europe_PMC"},{"url":"http://dx.doi.org/10.1371/journal.pone.0057842","host_type":""},{"url":"https://dx.doi.org/10.1371/journal.pone.0057842","host_type":""}],"fields_of_study":["Cellular transport and secretion","Neurobiology and Insect Physiology Research","Lipid Membrane Structure and Behavior","0301 basic medicine","0303 health sciences","03 medical and health sciences"],"mesh_terms":["Animals","Mutation","Synaptic Vesicles","Caenorhabditis elegans","Caenorhabditis elegans Proteins","Vesicular Transport Proteins","Synaptotagmins","Mice"],"keywords":["Synaptotagmin 1","Synaptotagmin I","Biology","Synaptobrevin","Vesicle fusion","Syntaxin","Cell biology","Synaptic vesicle","Neurotransmission","Biophysics","Vesicle","Biochemistry","Receptor","Science","Q","R","Vesicular Transport Proteins","Mice","Synaptotagmins","Mutation","Medicine","Animals","Synaptic Vesicles","Caenorhabditis elegans","Caenorhabditis elegans Proteins","Research Article"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-14T12:47:48.955847Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
