What distinguishes the Rab family of proteins from the SNARE family of proteins? Rab proteins are involved in vesicle transport and act by recognizing and binding their complimentary proteins on specific target membranes. Rab proteins are found on the surfaces of transport vesicles, while SNARE proteins are found on the surfaces of target membranes. The Rab family of proteins bind specific effector molecules in order to perform their functions of membrane recognition, tethering and docking. The specific type of SNARE proteins found on each membrane in the endomembrane system is unique, conferring membrane specificity.
