Published in 2017 at "Protein Science"

DOI: 10.1002/pro.3116

Abstract: Soluble N‐ethylmaleimide‐sensitive factor attachment protein receptors (SNAREs) are universal molecular engines that drive membrane fusion. Particularly, synaptic SNAREs mediate fast calcium‐triggered fusion of neurotransmitter‐containing vesicles with plasma membranes for synaptic transmission, the basis of all… read more here.
