... research has focused primarily on postsynaptic targets. Recent research using the model organism Caenorhabditis elegans has determined a role for specific proteins (Munc18-1 and Rab3) and processes (synaptic vesicle recruitment and fusion) in transducing the presynaptic effects of ethanol. In the present...

... is controlled by dense F-actin (filamentous actin) beneath the plasma membrane. Recently, we found that, in the absence of Munc18-1, the number of docked vesicles and the thickness of cortical F-actin are affected. In the present paper, I discuss the possible mechanism by which Munc18-1 modulates cortical F...

... release in mice, Munc18-1, results in a complete block of exocytosis. Manipulation of Munc18-1 protein levels in neurons and adrenal chromaffin cells argues for a positive role of this protein in vesicle secretion, as overexpression results in an increase in vesicle secretion. A decrease in Munc18-1...
