SNARE complex oligomerization by synaphin/complexin is essential for synaptic vesicle exocytosis

Article Abstract:

Research has been conducted on the cytosolic protein synaphin/complexin binding to syntaxin within the syntaxin and synapto-some-associated protein receptor (SNARE) complex. Results indicate that the synaphin promotes SNAREs to form pre-complexes which oligomerize into higher order structures.

Inhibition of SNARE complex assembly differentially affects kinetic components of exocytosis

Article Abstract:

Results demonstrate that soluble NSF attachment protein receptors (SNARE) complex into loose or tight assembly before exocytosis can occur. The data further indicate that the two forms of SNARE are interconvertible and in presence of an inhibitor, the loose state is favored

Nitric oxide regulates exocytosis by S-nitrosylation of N-ethylmaleimide-sensitive factor

Article Abstract:

Research has been conducted on nitric oxide which inhibits vascular inflammation. The authors report that nitric oxide inhibits Weibel-Palade bodies' exocytosis via regulation of the N-ethylmaleimide-sensitive factor activity.
