Function

LEC1_PLAAG Lectin specific for high mannose N-glycans, recognizes the branched moiety of these glycans. Does not recognize other types of N-glycans or monosaccharides. Agglutinates trypsin-treated rabbit erythrocytes. Does not require divalent cations for activity. Inhibits HIV replication in MT4 cells with an EC(50) of 45 nM. Binds to the HIV envelope glycoprotein gp120.^{[1] [2]}
