INTERFERON RECEPTOR BINDING PEPTIDES

摘要

A polypeptide for use as an interferon receptor-binding peptide, said polypeptide selected from the group of peptides having an amino acid sequence substantially of the formulae; CYS-LEU-LYS-ASP - ARG-HIS-ASP; ASP-GLU-SER-LEU-LEU- GLU-LYS-PHE-TYR-THR-GLU-LEU-TYR-GLN-LEU-ASN-ASP; ASN-GLU-THR-ILE-VAL-GLU-ASN - LEU-LEU-ALA- ASN-VAL-TYR-HIS-GLN-ILE-ASN-HIS; TYR-LEU-THR-GLU-LYS-LYS-TYR-SER-PRO-CYS-ALA ; TYR-PHE-GLN- ARG-ILE-THR-LEU-TYR-LEU-THR-GLU-LYS-LYS-TYR-SER-PRO-CYS-ALA; TYR-PHE-GLN-ARG - ILE-THR-LEU- TYR; and GLU-LEU-TYR-GLN-GLN-LEU-ASN-ASP. The polypeptides are useful for delivering a pharmaceutically active drug to a cell.
