Abstract: D-peptidic compounds that specifically bind to VEGF are provided. Also provided are multivalent D-peptidic compounds that include two or more of the domains connected via linking components. The multivalent (e.g., bivalent, trivalent, tetravalent, etc.) compounds can include multiple distinct domains that specifically bind to different binding sites on a target protein to provide for high affinity binding to, and potent activity against, the VEGF target protein. D-peptidic GA and Z domains that find use in the multivalent compounds are also provided, which polypeptides have specificity-determining motifs (SDM) for specific binding to VEGF (e.g., VEGF-A). Since the target protein is homodimeric (e.g., VEGF-A), the D-peptidic compounds may be similarly dimeric, and include a dimer of multivalent (e.g., bivalent) D-peptidic compounds. Also provided are methods for treating a disease or condition associated with VEGF or angiogenesis in a subject such as age-related macular degeneration (AMD) or cancer.

Abstract: Scaffolded peptidic libraries and methods of screening the same for specific binding to a target protein are provided. Each library includes distinct peptidic compounds that include a scaffold domain and a distinct variable domain. A variety of libraries are provided where each library is based on an underlying peptidic scaffold having a structural motif. In some embodiments, the peptidic scaffold is a small protein having a protein-protein interaction surface. Libraries of polynucleotides that encode a variety of peptidic compounds are provided. These libraries find use in a variety of applications in which specific binding to target molecules, e.g., target proteins is desired. Also provided are methods of making the libraries and methods of screening the libraries for binding to a target.

Abstract: GB1 peptidic compounds that specifically bind to a hemagglutinin target protein, and libraries that include the same, as well as methods of making and using the same, are provided. Also provided are methods and compositions for making and using the compounds. Also provided are hemagglutinin mimics and fragments and methods of using the same, including methods of screening for GB1 peptidic compounds and methods of using conjugates the mimics as influenza A vaccines. Aspects of the invention include methods of screening libraries of L-peptidic compounds for specific binding to a D-peptidic hemagglutinin target protein. Once a L-peptidic compound has been identified that specifically binds to the D-peptidic hemagglutinin target protein, the D-enantiomer of the selected L-peptidic compound may be produced. In some embodiments, the D-enantiomer of the selected L-peptidic compound binds to, and in some instances, neutralizes influenza virus particles.
