Abstract: A novel method of detecting and characterizing protein-peptide interactions is provided, which can be used for isolating peptides and proteins, respectively, as well as in drug screening and development.
Abstract: The present invention generally relates to a method for identifying and cloning nucleic acid molecules encoding a new class of proteins or fragments thereof, capable of interacting with proteins associated with the Human Hepatitis C virus (HCV) and thus being suitable either alone or in complex with the HCV protein for serving as a target for the development of antiviral drugs. In this context, the present invention provides novel HCV-interacting proteins and complexes as well as antibodies which specifically recognize and bind to the complex or to specific domains of HCV proteins.
