Competing Interests

The authors have read the journal's policy and the authors of this manuscript have the following competing interests: Benjamin Hackel, Daniel Woldring, and Hong Zhou are inventors on U.S. Provisional Patent Application 62/186,498 (“Compositions and methods that involve protein scaffolds that specifically bind to hepatocyte growth factor receptor”), filed by the University of Minnesota, related to ligands engineered to bind MET. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
