NAPA Human Recombinant produced in E. Coli is a single, non-glycosylated polypeptide chain containing 315 amino acids (1-295) and having a molecular mass of 35.3 kDa. NAPA is fused to 20 amino acid His Tag at N-terminus and purified by standard chromatography techniques. NAPA is part of the SNAP (Soluble NSF Attachment Protein) family. SNAPs, acting together with SNAREs (SNAP receptors) and the N-ethylmaleimide-sensitive fusion protein (NSF), are necessary for the fusion of transport vesicles to their objective membranes in synaptic transmission, intra-Golgi transport, endosome-to-endosome fusion and transcytotic vesicles-to-plasma membrane transport. NAPA is in charge of the binding of NSF and therefore the formation of a 20S fusion particle.
