SNAREs are transmembrane proteins involved in catalysing membrane fusion events in cells. There are two types of SNARE protein, v-SNARE and t-SNARE. The v-SNARE is attatched to the membrane of the vesicle to be released. The t-SNARE is integrated into the target organelles membrane. The v-SNARE's have complimentary shaped t-SNAREs which they bind to.
