Abstract

The present invention provides antigen-binding polypeptides, including bi-specific antigen-binding polypeptides, that specifically bind to a first and a second target antigen with high affinity. The present invention also provides novel antigen-binding polypeptides that specifically bind to HER2 and antagonize HER2 activation. The invention also provides nucleic acids encoding the antigen-binding polypeptides, recombinant expression vectors and host cells for making such antigen binding polypeptides. Methods of using antigen-binding polypeptide of the invention to treat disease, including cancer, are also encompassed by the invention.
