EC-3, an inhibitor of .alpha.4.beta.1 and .alpha.4.beta.7 integrins

   
   

This invention relates to the identification, purification, and characterization of a novel heterodimeric disintegrin, EC-3, from Echis carinatus viper venom. EC-3 inhibits .alpha.4 integrins in an RGD-independent manner. The invention further relates to methods of using EC-3, or a biologically active fragment or derivative thereof, to inhibit the interaction between cells expressing .alpha.4 integrins and cellular ligands.

Этот вымысел относит к идентификации, очищению, и характеризации disintegrin романа heterodimeric, EC-3, от venom змеенжша carinatus Echis. EC-3 блокирует integrins alpha.4 в РГД-nezavisimo образе. Вымысел более дальнейший относит к методам использования EC-3, или биологически активно части или производному thereof, заблокировать взаимодействие между клетками выражая integrins alpha.4 и клетчатые ligands.
