Patent ID: 8735546

Claim:
A binding protein comprising first and second polypeptide chains, each independently comprising VD1-(X1)n-VD2-C-(X2)n, wherein VD1 is a first variable domain; VD2 is a second variable domain; C is constant domain; X1 is a linker; X2 is an Fc region; n is 0 or 1; wherein the VD1 domains on the first and second polypeptide chains form a first functional target binding site and the VD2 domains on the first and second polypeptide chains form a second functional target binding site, wherein the binding protein is capable of binding IL-17, and wherein the variable domains that form a functional target binding site for IL-17 comprise CDRs 1-3 from SEQ ID NO: 40 and CDRs 1-3 from SEQ ID NO: 41.
