Napa - N-ethylmaleimide sensitive fusion protein attachment protein alpha

Enables syntaxin binding activity. Involved in regulation of synaptic vesicle priming and synaptic vesicle priming. Acts upstream of or within several processes, including SNARE complex disassembly; apical protein localization; and nervous system development. Located in glutamatergic synapse. Part of synaptobrevin 2-SNAP-25-syntaxin-1a complex. Is expressed in central nervous system; peripheral nervous system ganglion; and retina. Orthologous to human NAPA (NSF attachment protein alpha).
