  • Trimeric glycoproteins (at least 11 types) with integrin binding site
  • Defects in laminin proteins cause skin blistering and myocardial diseases
  • Antibodies to laminin inhibit lung branching morphogenesis
  • Production of alpha-1 laminin by epithelial cells and mesenchymal cells depends on extent of mesenchymal and epithelial contact with each other; modulates mesenchymal cell shape
