The GAL1 (galectin-1) recombinant protein is a β-galactoside-binding lectin widely studied for its roles in cellular regulation and immune modulation. Produced through recombinant DNA technology, it is expressed in systems like *E. coli* or mammalian cells, ensuring high purity and consistency for research and therapeutic applications. GAL1 is a homodimeric protein (~14.5 kDa per subunit) with a conserved carbohydrate recognition domain (CRD) critical for binding glycoconjugates on cell surfaces or extracellular matrices.
Functionally, GAL1 participates in cell adhesion, proliferation, apoptosis, and immune tolerance. It modulates signaling pathways such as Ras/ERK and PI3K/AKT, influencing cancer progression and neuronal survival. In immunology, GAL1 suppresses pro-inflammatory T-cell responses while promoting regulatory T-cell (Treg) activity, making it a key player in autoimmune disease mitigation and tumor immune evasion. Its ability to induce apoptosis in activated T cells and thymocytes highlights its dual role in immune homeostasis.
Research applications include studying cancer metastasis, neuroinflammation, and autoimmune disorders like multiple sclerosis. Therapeutically, recombinant GAL1 is explored for anti-inflammatory therapies, wound healing, and cancer immunotherapy, though its context-dependent pro- or anti-tumor effects require careful evaluation. Challenges remain in optimizing delivery methods and understanding tissue-specific glycan interactions. Despite this, GAL1’s versatility positions it as a promising target for both mechanistic studies and clinical development.
