Rab proteins are members of the Ras GTPase superfamily and are known regulators of membrane-trafficking events. There is an increasing body of evidence that links Rab-regulated recycling pathways ...

Rab proteins achieve this by reversibly associating with lipid membranes through a process that is known as Rab membrane cycling. Active GTP-bound prenylated Rab proteins are present in membranes.

Key regulators of this process include the Rab family of GTPases, SNARE proteins, and the endosomal sorting complex required for transport (ESCRT). Read the full story here.
