ABSTRACT:
The invention relates to a recombinant receptor, comprising a ligand-binding domain and a signaling domain that comprises a heterologous bait polypeptide, which receptor is inactivated by binding of a prey polypeptide to the heterologous bait peptide, either in presence or absence of a ligand binding to the ligand-binding domain. The receptor is activated by addition of a compound that disrupts the bait-prey interaction. The invention also relates to a method of screening compounds that disrupt compound-compound binding using the recombinant receptor.
