RABL3. or RAB-like protein 3. is a member of the RAB family of small GTPases, which are key regulators of intracellular vesicle trafficking and membrane dynamics. Unlike canonical RAB proteins, RABL3 shares structural homology but exhibits distinct functional characteristics. It contains conserved GTP-binding domains and cycles between an active GTP-bound and inactive GDP-bound state, facilitating interactions with effector molecules to coordinate cargo transport. RABL3 is implicated in diverse cellular processes, including protein secretion, autophagy, and organelle positioning. Recent studies highlight its role in regulating the secretory pathway, particularly in the maturation and trafficking of insulin granules in pancreatic β-cells, suggesting a link to metabolic disorders. Additionally, RABL3 has garnered attention in cancer biology due to its overexpression in certain malignancies, such as pancreatic ductal adenocarcinoma, where it promotes tumor progression by enhancing cell proliferation and invasiveness. Notably, germline mutations in RABL3 have been associated with hereditary cancer predisposition syndromes, implicating it as a potential oncogenic driver. Despite these advances, the precise molecular mechanisms underlying RABL3’s functions remain incompletely understood. Ongoing research aims to elucidate its interactome, subcellular localization, and signaling pathways, with therapeutic targeting of RABL3 emerging as a promising avenue for cancer treatment. Overall, RABL3 represents a critical yet understudied node in cellular trafficking networks and disease pathogenesis.
