THREE-DIMENSIONAL STRUCTURE OF THE RGD-CONTAINING NEUROTOXIN HOMOLOGUE, DENDROASPIN
Structural highlights
Function3SPM_DENJA Inhibits ADP-induced platelet aggregation and inhibits the binding of purified platelet fibrinogen receptor alpha-IIb/beta-3 (ITGA2B/ITGB3) to immobilized fibrinogen (PubMed:1591238). Has also been described to inhibit cell adhesion to fibrinogen, fibronectin, laminin and collagen (PubMed:11336631, PubMed:16798616).[1] [2] [3] Evolutionary ConservationCheck, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedDendroaspin is a short chain neurotoxin homologue from the venom of Elapidae snakes, which lacks neurotoxicity. Unlike neurotoxins, it contains an Arg-Gly-Asp-(RGD)-motif and functions as an inhibitor of platelet aggregation and platelet adhesion with comparable potency to the disintegrins from the venoms of Viperidae. We have determined the structure of dendroaspin in solution using NMR spectroscopy. The structure contains a core similar to that of short chain neurotoxins, but with a novel arrangement of loops and a solvent-exposed RGD-motif. Dendroaspin is thus an integrin antagonist with a well defined fold different from that of the disintegrins, based on the neurotoxin scaffold.
