abstract：:Although some of the principles of N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) function are well understood, remarkably little detail is known about sec1/munc18 (SM) protein function and its relationship to SNAREs. Popular models of SM protein function hold that these proteins promote or main...
