Functioni

The disintegrin ocellatusin-10c1 is a poor inhibitor of platelet aggregation. The disintegrin inhibits the adhesion of cells expressing the RGD-dependent integrin alpha-5/beta-1 (ITGA5/ITGB1) to immobilized fibronectin. Inhibition on alpha-2b/beta-3 (ITGA2B/ITGB3) is low, and there is no inhibition on alpha-1/beta-1 (ITGA1/ITGB1), alpha-2/beta-1 (ITGA2/ITGB1) and alpha-6/beta-1 (ITGA6/ITGB1) (By similarity).By similarity
The short monomeric disintegrin ocellatusin inhibits ADP-induced platelet aggregation (IC50=168 nM). Inhibits alpha-5/beta-1 (ITGA5/ITGB1) integrin and induces the expression of a ligand-induced binding site epitope on beta-1 integrin subunit. Has a direct chemotactic stimulus on human neutrophils in vitro.1 Publication
