Priming is the process by which vesicles become available for fusion at nerve terminals and it is modulated by numerous proteins and second messengers. One of the prominent members of this diverse family is Tomosyn. Tomosyn has been identified as a Syntaxin-binding protein; it inhibits vesicle priming, but its mode of action is not fully understood. Tomosyn's inhibitory activity depends on its N-terminal WD40-repeat domain and is regulated by the binding of its SNARE-motif to Syntaxin. The present review describes new physiological information on Tomosyn's function and addresses possible interpretations of these results in the framework of the recently described crystal structure of the yeast Tomosyn homolog Sro7. We also present possible molecular scenarios for vesicle priming and the involvement of Tomosyn in these processes.
