Lectin (PubMed:24361256). Induces paw edema in mice (PubMed:22368061). Has a weak vasorelaxant effect on rat aorta (PubMed:24361256). Has anti-inflammatory and anti-nociceptive effects (PubMed:19153712). Homotetramer; dimer of dimers. Concanavalin A-like lectins of the Diocleinae subtribe undergo proteolytic processing referred to as circular permutation. The propeptide is split into an N-terminal and a C-terminal part, the gamma and beta chain, respectively. These are then religated in beta-gamma order to form the mature alpha chain. The beta and gamma chains can often be detected in cell extracts. Residues 1-118 of the mature chain, as displayed here, probably constitute the beta chain in the propeptide, residues 119-237 the gamma chain. Binds one manganese (or other transition metal) ion and one calcium ion (PubMed:24361256). The metal ions are essential for the saccharide-binding and cell-agglutinating activities (Probable). Belongs to the leguminous lectin family.
