N-ethylmaleimide sensitive factor (NSF) is a regulator of plasma membrane rupture and necrotic cell death
… We targeted N-ethylmaleimide sensitive factor (NSF) due to its requirement in SNARE recycling, lack of gene homologs, and redox sensitivity. Deletion of Nsf protected against membrane rupture induced by various necrotic stimuli, yet did not influence apoptosis, suggesting specificity in …

Insights into the Functions of Munc18-1 in Neurotransmitter Release
… complex on liposomes in the presence of NSF/α-SNAP/ATP. When NSF/α-SNAP were incorporated in the lipid mixing assays between synaptobrevin-liposmes and syntaxin-1/SNAP-25-liposomes, Munc18-1 together with Munc13 activate lipid mixing that is inhibited by NSF/α-SNAP. These results suggest …

Understanding the Role of Non-federal Funding Match on the Effectiveness of a U.S. Strategy to Strengthen Academic Research Competitiveness Nationwide
NSF EPSCoR is a policy intervention designed more than 40 years ago to help U.S. states increase their academic research competitiveness, measured principally at the time by their shares of federal research funding. This study used a comparative approach to focus on a cohort of eleven U.S. states …

Dissecting Roles for the Macromolecular Machinery Involved in Neurotransmitter Release
… trans-SNARE complexes can be disassembled by NSF-αSNAP. I showed that trans-SNARE complex formation in the presence of NSF-αSNAP requires both Munc18-1 and Munc13-1, and is facilitated by synaptotagmin-1. I proposed a model whereby Munc18-1 and Munc13-1 are critical for mediating vesicle …
