Contortrostatin is a homodimeric disintegrin from snake venom. We have shown that contortrostatin binds to integrins alphaIIbbeta3, alpha5beta1, and alphavbeta3. We now use several criteria to demonstrate the binding of contortrostatin to alphavbeta5. First, incubation of T24 cells, which express alphavbeta3 and alphavbeta5, with antibody against alphavbeta3 failed to completely inhibit adhesion of cells to vitronectin. However, pretreatment of the cells with contortrostatin or the combination… CONTINUE READING
