  1. What are the EC proteins?
    • collagen
    • fibronectin
    • proteoglycan
    • laminin
  2. Fibronectin: 
    -consists of what?
    - made of what?
    • a linear array of building blocks (Fn-modules)
    • made of a sequence of about 30 independent FN-modules, which combine to make 5-6 larger functional domains
  3. In fibronectin, each of the two polypeptide chains that make up a fibronectin molecule contain what?
    • binding sites for components of hte ECM that help stabilize the structure; enhanced by mechanical forces that pull on the fibrous proteins--> unfold--> reveal binding sites
    • binding sites for receptors on the cell surface that help stabilize attachment to the cell
