Scientific and standardization committee communications: Classification and nomenclature of disintegrins isolated from snake venoms

Abstract

Viper venoms from the Elapidae, Hydrophiidae, Atractaspididae, Viperidae and Colubridae families contain at least 25 separate classes of biologically active compounds, including enzymes and non-enzymatic molecules. Nomenclature standardization of these by structure and function has been reported for prothrombin activators. No such agreement has been made for the nomenclature and classification of disintegrins. At the 51st Annual SSC Meeting in Sydney Australia (August 2005), we reported the variety of names given to the 78 disintegrins then known, and proposed a nomenclature standardization method for the naming of future members in this protein family. The summary of these recommendations will provide guidance as disintegrin discoveries move beyond high pressure liquid chromatography (HPLC) separation methods to mass spectrometry, proteomics and cloned cDNA. © 2007 International Society on Thrombosis and Haemostasis.
