Rab7A Protein is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The RAB7A gene encodes the RAB7A (Ras-related protein RAB-7A), a member of the RAB GTPase family, small GTP-binding protein. This protein localizes primarily to Late endosomes, Lysosomes.
RAB7A is a small GTPase that regulates late endosomal trafficking and lysosomal function. RAB7A cycles between active (GTP-bound) and inactive (GDP-bound) states, with GTP hydrolysis controlling its activity. Active RAB7A recruits effector proteins that mediate membrane fusion, including HOPS complex components. RAB7A is essential for late endosome-lysosome fusion, autophagosome-lysosome fusion during late-stage autophagy, and transport from early to late endosomes. In neurons, RAB7A plays critical roles in retrograde axonal transport, neurotrophin signaling (particularly BDNF/TrkB), and synaptic function. RAB7A mutations cause Charcot-Marie-Tooth disease type 2B, and dysregulation contributes to Parkinson's and Alzheimer's disease pathogenesis.
Charcot-Marie-Tooth Disease Type 2B (CMT2B), Parkinson's Disease, Alzheimer's Disease, Huntington's Disease are associated with mutations or dysregulation of RAB7A.
