Ligand-binding specificities of laminin-binding integrins: A comprehensive survey of laminin–integrin interactions using recombinant α3β1, α6β1, α7β1 and α6β4 integrins

The interactions of cells with basement membranes are primarily mediated via the engagement of laminins by a group of integrin family proteins, including integrins alpha3beta1, alpha6beta1, alpha7beta1 and alpha6beta4. To explore the ligand-binding specificities of these laminin-binding integrins, we produced these integrins, including two alpha7beta1 splice variants (alpha7X1beta1 and alpha7X2beta1), as soluble recombinant proteins and...
