**Background of Reg2 Recombinant Protein**
The Regenerating Gene (Reg) family, initially identified for its role in pancreatic β-cell regeneration, encodes secreted proteins involved in cell proliferation, differentiation, and tissue repair. Reg2. a member of this family, is primarily expressed in pancreatic acinar cells, neurons, and certain immune cells. It shares structural homology with other Reg proteins, including a conserved calcium-dependent carbohydrate-binding motif (C-type lectin domain), suggesting roles in cell adhesion, signaling, or pathogen recognition.
Reg2 gained attention due to its upregulated expression during pancreatic injury, inflammation, or metabolic stress, implicating it in tissue repair and adaptive responses. Studies in rodent models revealed that Reg2 promotes β-cell survival and regeneration, potentially through interactions with specific receptors like EXTL3 (exostosin-like glycosyltransferase 3), which activates pro-survival pathways such as PI3K/Akt and ERK. Beyond diabetes research, Reg2 is implicated in neuroprotection and nerve regeneration, as it enhances neuronal survival and axonal growth *in vitro* and in nerve injury models.
Recombinant Reg2 protein, produced via bacterial or mammalian expression systems, retains bioactivity and is widely used to dissect its molecular mechanisms. However, challenges like low solubility and stability in its native form have driven engineering efforts, including fusion tags or modified purification strategies. Recent studies also explore its paradoxical roles in cancer, where Reg2 may either inhibit tumor growth or promote metastasis depending on context.
Overall, Reg2 recombinant protein serves as a critical tool for studying regenerative medicine, metabolic disorders, and neural repair, with therapeutic potential awaiting further validation in preclinical and clinical settings.
