Grouped By:  Matching UniProtKB accession

UniProtKB description:  Lectin that recognizes O-linked galactose-beta-1,3-N-acetylgalactosamine, a disaccharide (Thomsen-Friedenreich antigen or T-disaccharide), present on cell surface glycoproteins. Can also bind galactose-beta-1,3-N-acetylglucosamine. Does not bind monosaccharides. Can be internalized by clathrin-coated vesicles after binding to surface glycoproteins. After internalization it inhibits nuclear import of nuclear localization signal dependent proteins. Inhibits proliferation of malignant cells without cytotoxicity for normal cells.
