| Addtional Information | FUNCTION:Glucose/D-mannose/rhamnose specific lectin. Has hemagglutinating activity towards rabbit erythrocytes. Has mitogenic activity towards murine splenocytes that is inhibited by glucose. Inhibits HIV-1 reverse transcriptase with an IC(50) of 35uM. Has a potent antiproliferative activity against L1210 leukemia cells in vitro that is not inhibited by glucose. Inhibits translation in cell-free rabbit reticulocyte system with an IC(50) of 2.08uM. Lacks anti-fungal activity against M.arachidicola, B.cenera and F.oxysporum.SUBUNIT:Homotetramer.PTM:The mature chain consists of residues 164-281 followed by 30- 148. To form a mature chain the precursor undergoes further post- translational modification after removal of the signal sequence; cleavage after Asn at positions Asn-148, Asn-163, and Asn-281 is followed by transposition and ligation (By formation of a new peptide bond) of residues 164-281 and 30-148.MISCELLANEOUS:Binds one manganese (or other transition metal) ion and one calcium ion. The metal ions are essential for the saccharide-binding and cell-agglutinating activities.SIMILARITY:Belongs to the leguminous lectin family. |
