Endostatin binds to the integrins alphaVbeta3, alphaVbeta5, alpha5beta1 (Rehn et al. 2001, Faye et al. 2009) and alpha3beta1 (Su et al. 2012). Endostatin is the cleaved non-collagenous C ternminal domain of collagen alpha-1(XVIII) a member of the multiplexin family. It inhibits endothelial cell migration, proliferation, and angiogenesis (Fu et al. 2009).
