A number of small Rab GTPases have been found to regulate vesicle trafficking to ensure that cargos are delivered to the correct destination.[30] Myosin V has been shown to associate with cargo vesicles in a Rab‐dependent manner.[31] Inhibition of Rab7 has been shown to impede migration of cancer cells such as MDA‐MB‐231.[32]. The gene discussed is RAB6A; the disease is cancer.
