摘要：
Galectin-1 polypeptide variants that include a mutation of the histidine residue corresponding to position 52 of the full-length amino acid sequence of native human Gal-1 as shown in SEQ ID NO: 1, the mutation being a substitution of the histidine to tyrosine or asparagine, providing resistance to acidosis otherwise resulting in deactivation of the native human Gal-1. The Galectin-1 polypeptide variants may include one or more additional mutation(s) of the cysteine residue corresponding to a position selected from 2, 16, 88, or combinations thereof of the full-length amino acid sequence of native human Gal-1 as shown in SEQ ID NO: 1, the additional mutation being a substitution of the cysteine to serine, and providing resistance to oxidation.
