Identification of carbohydrate-binding proteins from mouse and human fibroblasts

Year: 1983

Type: article

Abstract: Three carbohydrate-binding proteins (Mr 35 000, 16 000 and 13 500) were isolated from extracts of mouse 3T3 fibroblasts by affinity chromatography on polyacrylamide beads to which was covalently bound the ligand 6-aminohexyl 4-beta-D-galactosyl-2-acetamido-2-deoxy-beta-D-glucopyranoside. None of these proteins bind to polyacrylamide beads coupled with either 6-aminohexanol or 6-aminohexyl beta-D-galactopyranoside. Therefore they appear to be carbohydrate-binding proteins specific for galactose-terminated glycoconjugates. A carbohydrate-binding protein was also purified from extracts of human foreskin fibroblasts. This protein (Mr 35000) may represent the human counterpart of the mouse protein of similar Mr and binding properties.
