Two highly homologous dimeric disintegrins, CC5 and CC8, have been isolated from the venom of the North African sand viper Cerastes cerastes. CC5 is a homodimer containing an RGD motif in its subunits. CC8 is a heterodimer. The CC8A and CC8B subunits contain RGD and WGD tripeptide sequence in their respective integrin-binding loops. Both CC5 and CC8 inhibited platelet aggregation and the adhesion of cells expressing integrins alphaII(b)beta3, alpha(v)beta3, and alpha5beta1 to appropriate… CONTINUE READING
