Description
Alpha, beta and gamma SNAPs, also known as soluble NSF attachment proteins, have apparent molecular weights on SDS PAGE of 35, 36 and 39 kDa, respectively. SNAP proteins mediate the association of NSF to membranes during vesicle fusion reaction, and play a prominent role in synaptic vesicle fusion. In addition, beta SNAP interacts with synaptotagmin and may be involved in calcium regulated exocytosis. SNAP was identified as being required for vesicle fusion in intra Golgi transport reaction in vitro. Alpha SNAP mediates the association of NSF to membranes during vesicle fusion reaction, and plays a prominent role and in synaptic vesicle fusion. Together with synaptotagmin and NSF, alpha SNAP modulates the interaction of SNAP25, VAMP, and syntaxin in, an ATP dependent manner, to form a complex with a sedimentation coefficient of 20 S. This complex may represent an intermediate involved in synaptic vesicle docking and fusion.
