603698 Disclosed is 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 a constant domain; XI1is a linker; X2 is an Fc region; and 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; and wherein the binding protein is capable of binding TNF and PGE2, wherein: (a) the variable domains that form a functional binding site for TNF comprise EVQLVESGGGLVQPGRSLRLSCAASGFTFDDYAMHWVRQAPGKGLEWVSAITWNSGHIDYADSVEGRFTISRDNAKNSLYLQMNSLRAEDTAVYYCAKVSYLSTASSLDYWGQGTLVTVSS and DIQMTQSPSSLSASVGDRVTITCRASQGIRNYLAWYQQKPGKAPKLLIYAASTLQSGVPSRFSGSGSGTDFTLTISSLQPEDVATYYCQRYNRAPYTFGQGTKVEIKR; and (b) the variable domains that form a functional binding site for PGE2 comprise EVQLVQSGAEVKKPGASVKVSCKASGYTFTKYWLGWVRQAPGQGLEWMGDIYPGYDYTHYNEKFKDRVTLTTDTSTSTAYMELRSLRSDDTAVYYCARSDGSSTYWGQGTLVTVSS and DVLMTQTPLSLPVTPGEPASISCTSSQNRleVHSNGNTYLEWYLQKPGQSPQLLIYKVSNRFSGVPDRFSGSGSGTDFTLKISRVEAEDVGVYYCFQVSHVPYTFGGGTKVEIKR |
