Abstract

This invention relates to modular proteins that interact with one or more target molecules. The chimeric proteins comprise two or more repeat domains, such as tetratricopeptide repeat domains; inter-repeat loops linking the repeat domains; and one or more peptide ligands. Each peptide ligand is located in an inter-repeat loop or at the N or C terminus of the chimeric protein. The peptide ligands may include heterologous peptidyl binding motifs, such as short linear motifs (SLiMs). Chimeric proteins with various configurations and methods for their production and use are provided.
