Lectin MVL

UniProtKB accession:  Q9RHG4

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Carbohydrate-binding protein that binds oligomannosides such as Man(6)GlcNAc(2) with sub-micromolar affinities. The specificity of MVL is unique in that its minimal target comprises the Man-alpha-(1->6)-Man-beta-(1->4)-GlcNAc-beta-(1->4)-GlcNAc tetrasaccharide core (Man(2)A) found in N-linked oligomannosides. Displays hemagglutininating activity on rabbit, horse and hen erythrocytes. This activity is inhibited by yeast mannan. Does not bind mono- and disaccharides. Inhibits HIV-1 envelope-mediated cell fusion at nanomolar concentrations through carbohydrate-mediated interactions with high-mannose residues on the surface of the HIV envelope glycoprotein gp120.
