RAB7A is a member of the Rab GTPase family, a subgroup of the RAS superfamily of small GTP-binding proteins. It plays a critical role in regulating intracellular membrane trafficking, particularly in the late endosomal and lysosomal pathways. As a key coordinator of vesicle transport, RAB7A is involved in endosome maturation, autophagosome-lysosome fusion, and the degradation of biomaterials through both endocytic and autophagic pathways. It also participates in signaling pathways related to cell survival, apoptosis, and immune responses. Dysregulation of RAB7A has been linked to various diseases, including neurodegenerative disorders (e.g., Charcot-Marie-Tooth disease), cancer metastasis, and pathogen infection mechanisms.
Recombinant RAB7A protein is produced using genetic engineering techniques, often expressed in bacterial (e.g., *E. coli*) or eukaryotic systems to ensure proper post-translational modifications. The recombinant form typically retains GTPase activity and structural features of the native protein, including conserved GTP-binding domains and effector interaction sites. Its production enables detailed biochemical studies, such as analyzing GTP/GDP binding kinetics, interactions with regulatory proteins (e.g., RILP, ORP1L), and functional assays in membrane fusion processes.
Researchers utilize recombinant RAB7A to investigate its role in cellular homeostasis, pathogen invasion (e.g., viral/bacterial subversion of endosomal pathways), and drug delivery systems targeting lysosomal disorders. It also serves as a tool for screening small-molecule modulators of Rab7 activity, with therapeutic potential for diseases involving trafficking defects. Quality assessments often include SDS-PAGE, Western blotting, and activity-based assays to confirm purity and functionality. As membrane trafficking research expands, recombinant RAB7A remains a vital resource for both basic science and translational applications.
