Abstract:
1. A screening method for a substance that regulates a function associated with target protein Y, which method comprises the following steps (a) to (c): (a) a step for bringing a test substance and bioactive substance X into contact with target protein Y; (b) a step for measuring the binding level of bioactive substance X to the protein in the presence of the test substance, and comparing this binding level with the binding level of bioactive substance X to the protein in the absence of the test substance; and (c) a step for selecting a test substance that alters the binding level of bioactive substance X to the protein on the basis of the results of the comparison in step (b) above, wherein bioactive substance X is cefaclor and target protein Y is a protein containing the amino acid sequence of SEQ ID NO. 2.
