SNAP-25 (synaptosomal-associated protein 25 kDa) is a target for botulinum neurotoxins A and E, which both inhibit neurotransmitter release, and was recently identified together with syntaxin and synaptobrevin as receptors for NSF and α-SNAP. We show that SNAP-25 was enriched in the microsomal fract...
