Abstract |
We previously developed a stable form of galectin-9, an immunomodulatory animal lectin with a truncated linker peptide (G9Null), to overcome the protease sensitivity of wild-type galectin-9. G9Null is highly resistant to proteolysis, while the modification marginally improved the low solubility of the wild-type protein. To increase its solubility, we further modified the remaining linker region of G9Null. A 10-amino acid deletion with a single amino acid substitution resulted in an ∼400% increase in solubility and yield without an adverse effect on its biological activity. This mutant protein might be useful for large-scale recombinant production needed for evaluation of the therapeutic potential of galectin-9.
