Integrin receptor ligand binding
NettetIntegrins are more promiscuous than most adhesion receptors, as some bind to several protein ligands, and many matrix molecules bind to more than one integrin. For example, fibronectin binds to at least nine different integrins, and both laminin and von Willebrand factor bind at least five different integrins. NettetIntegrin α7β1 is a major laminin α2 receptor in skeletal myotubes and mature myofibers. Integrin α7β1 expression and localization is laminin α2 dependent (Vachon et al., …
