| Research Abstract |
Human a1-acid glycoprotein binds to a variety of drugs and therebyregulates their tissue distribution. AGP exists as a mixture of two genetic variants,the A and F1*S variants, which bind drugs with different selectivities. In this study,we determined crystal structures of the A variant in complex with two types of tricyclicdrugs, and revealed their binding modes in the pocket of the A variant. Also, we mutatedthe amino acid residues which are involved in drug binding, and examined the bindingproperties of the mutants.
