Abstract

Unravelling the SM-SNARE conundrum So-called SNARE proteins mediate and lend specificity to the fusion between different intracellular membranes. The SM proteins are universally required for intracellular vesicle fusion, yet their mechanism of action has long been enigmatic. Baker et al. have solved a piece of the puzzle by “capturing” SNAREs in the process of assembling into fusogenic complexes on the surface of an SM protein. The findings suggest exactly how and why SM proteins help vesicular fusion during intracellular membrane trafficking. Science , this issue p. 1111
