Function

[VM2RH_CALRH] Metalloproteinase rhodostoxin: snake venom metalloproteinase that impairs hemostasis in the envenomed animal (By similarity). Disintegrin rhodostomin: inhibit platelet aggregation induced by ADP, thrombin, platelet-activating factor and collagen. Acts by inhibiting fibrinogen interaction with platelet receptors GPIIb/GPIIIa (ITGA2B/ITGB3).

Publication Abstract from PubMed

The structure of kistrin, which is a member of a homologous family of glycoprotein IIb-IIIa (GP IIb-IIIa) antagonists and potent protein inhibitors of platelet aggregation, has been determined by two-dimensional nuclear magnetic resonance (NMR) spectroscopy. The 68-residue protein consists of a series of tightly packed loops held together by six disulfide bonds and has almost no regular secondary structure. Kistrin has an Arg-Gly-Asp (RGD) adhesion site recognition sequence important for binding to GP IIb-IIIa that is located at the apex of a long loop across the surface of the protein.
