NAPA, Recombinant, Human, aa1-295, His-Tag (N-ethylmaleimide-sensitive factor attachment protein, alpha)
NAPA is one of the SNAP (Soluble NSF Attachment Protein) family. SNAPs, 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. This protein mediates the binding of NSF and thus the formation of a 20S fusion particle. It is expressed in all mammalian tissues.
