P-Glycoprotein (P-gp), a transmembrane, ATP-dependent drug efflux transporter, has attracted considerable interest both with respect to its role in tumour cell multidrug resistance and in absorption-distribution and elimination of drugs. Although known since more than 30 years, the understanding of the molecular basis of drug/transporter interaction is still limited, which is mainly due to the lack of structural information available. However, within the past decade X-ray structures of several bacterial homologues as well as very recently also of mouse P-gp have become available. Within this review we give an overview on the current status of structural information available and on its impact for structure-based drug design.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
