Mouse monoclonal [4E4] to alpha SNAPSNAPs (soluble NSF attachment proteins), acting in concert with SNAREs (SNAP receptors) and the N-ethylmaleimide-sensitive fusion protein (NSF), are required for the fusion of transport vesicles to their target membranes in synaptic transmission, intra-Golgi transport, endosome-to-endosome fusion and transcytotic vesicles-to-plasma membrane transport. Vesicle-to-target membrane docking (initial contact) occurs when the vesicle SNARE binds to its cognate target membrane SNAP. a-SNAP (or b-SNAP in brain) then binds to this docking complex and mediates the binding of NSF and thus the formation of a 20S fusion particle. It is thought that, once NSF is bound, ATP hydrolysis by NSF initiates the fusion process. alpha SNAP is expressed in all mammalian tissues. |
