Abstract
A polypeptide is provided that excludes (a) a full-length mature TGF-.beta. molecule or precursor TGF-.beta. molecule or deletion variants of mature or precursor TGF-.beta. molecules in which from about 1 to 10 amino acid residues have been deleted, (b) a polypeptide of the sequence: Cys-Val-Arg-Gln-Leu-Tyr-Ile-Asp-Phe-Arg-Lys-Asp-Leu-Gly-Trp-Lys, and (c) a polypeptide of the sequence: Arg Asn-Leu-Glu-Glu-Asn-Cys-Cys-Val-Arg-Pro-Leu-Tyr-Ile-Asp-Phe-Arg-Gln-Asp-Le u, said polypeptide comprising an amino acid sequence that is based on conserved sequences in the family of TGF-.beta. molecules. Such polypeptides are particularly useful therapeutically as immunosuppressive agents when coupled to carrier proteins or crosslinked to form polymers.
