Function
Small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins playing a key role in the regulation of endo-lysosomal trafficking. Governs early-to-late endosomal maturation, microtubule minus-end as well as plus-end directed endosomal migration and positioning, and endosome-lysosome transport through different protein-protein interaction cascades. Plays a central role, not only in endosomal traffic, but also in many other cellular and physiological events, such as growth-factor-mediated cell signaling, nutrient-transportor mediated nutrient uptake, neurotrophin transport in the axons of neurons and lipid metabolism. Also involved in regulation of some specialized endosomal membrane trafficking, such as maturation of melanosomes, pathogen-induced phagosomes (or vacuoles) and autophagosomes. Plays a role in the maturation and acidification of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis. Plays a role in the fusion of phagosomes with lysosomes. Plays important roles in microbial pathogen infection and survival, as well as in participating in the life cycle of viruses. Microbial pathogens possess survival strategies governed by RAB7A, sometimes by employing RAB7A function (e.g. Salmonella) and sometimes by excluding RAB7A function (e.g. Mycobacterium). In concert with RAC1, plays a role in regulating the formation of RBs (ruffled borders) in osteoclasts. Controls the endosomal trafficking and neurite outgrowth signaling of NTRK1/TRKA (PubMed:11179213, PubMed:12944476, PubMed:14617358, PubMed:20028791, PubMed:21255211). Regulates the endocytic trafficking of the EGF-EGFR complex by regulating its lysosomal degradation. Involved in the ADRB2-stimulated lipolysis through lipophagy, a cytosolic lipase-independent autophagic pathway (By similarity). Required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413). Required for vesicular trafficking and cell surface expression of ACE2 (PubMed:33147445). May play a role in PRPH neuronal intermediate filament assembly (By similarity).

- Activity summary
Rab proteins including Rab9 Rab4 Rab5 RAB7 RAB10 and RAB8A are small GTPases that regulate intracellular vesicle trafficking. Rab proteins play key roles in membrane transport processes and are involved in various stages of vesicle budding movement docking and fusion. Each Rab protein has a specific mass for example Rab5 has approximately 24 kDa. These proteins are expressed in numerous tissues often with overlapping yet distinct expression patterns. They serve as endosome markers and localize to specific membrane compartments specializing in aiding the maturation movement and fusion of vesicles within cells.
- Biological function summary
These Rab proteins organize essential processes in cellular trafficking by interacting with effector proteins and elements of the cytoskeleton. They are integral to the formation of protein complexes required for vesicle tethering and fusion. Rab4 and Rab5 participate in early endosome dynamics coordinating endocytic pathways while RAB7 facilitates late endosome-lysosome trafficking. Rab9 assists in the movement of molecules from late endosomes to the trans-Golgi network. These proteins operate in concert ensuring precise regulation and timing in vesicular transport processes.
- Pathways
Rab proteins influence an array of intracellular signalling networks vital for cellular homeostasis. Rab5 participates prominently in the endocytosis pathway interacting with proteins like EEA1 (Early Endosome Antigen 1) to regulate vesicle fusion and sorting. RAB7 is heavily involved in the endo-lysosomal pathway important for lysosome biogenesis. This interaction optimizes cellular recycling and degradation processes. Rab8A affects exocytosis and is implicated in the secretory pathway especially in the context of polarized trafficking working alongside proteins like Sec4/RAB8.
- Associated diseases and disorders
Mutations or dysregulation of Rab proteins can contribute to neurodegenerative disorders and cancer. Rab5 and its partners are tied to the pathology of Alzheimer's disease through their role in the endocytic pathway where impaired function may lead to amyloid-beta plaque formation. Alterations in RAB7 activity associate with Charcot-Marie-Tooth disease type 2B where defective vesicular trafficking impacts neuronal function. These associations underline the importance of Rab proteins not only in normal cellular processes but in disease states as well.
