Recombinant Human LGALS9 protein, N-His

Background:Galectin-9 (Gal-9) is a lectin family member and is one of the tandem repeat-type galectins containing two carbohydrate recognition domains (CRD) connected by a linker region in a single peptide chain. The CRD is responsible for β-galactoside binding, and several binding partners for galectin-9 have been identified, including CD44, FGL, Gcgr, GLUT- 2, IgE, IgM, PDI, and Tim-3. Galectin-9 is constitutively presented in the small intestine, liver, uterine epithelial cells, skin epidermis, and esophageal epithelium. Galectin-9 contributing to cell growth, differentiation, adhesion, communication, and death. Accumulated evidence indicates that Gal-9 blockade promotes T cell immunity against tumors, suggesting that galectin-9 is a promising target for immunotherapy.
