a member of the RAB family of RAS-related GTP-binding proteins, important regulators of vesicular transport and are located in specific intracellular compartments. RAB7 has been localized to late endosomes and shown to be important in the late endocytic pathway. In addition, it has been shown to have a fundamental role in the cellular vacuolation induced by the cytotoxin VacA of Helicobacter pylori. Mutations in this protein cause Charcot-Marie-Tooth type 2B neuropathy. Note: This description may include information from UniProtKB.
