Synaptobrevin, Sphingolipids, and Secretion: Lube ‘n’ Go at the Synapse

For neurotransmitter release to occur, proteins and lipids have to work together. The classical view of this process is that a variety of proteins work hard to force the unwilling, fusion-aversive lipids into merging. In this issue of Neuron, a study by Darios et al. paints the opposite picture: a lipid metabolite stimulates the reluctant vSNARE synaptobrevin to engage in fusogenic protein complexes
