DIMERBOW: exploring possible GPCR dimer interfaces

G protein-coupled receptors (GPCRs) can form homo-, heterodimers and larger order oligomers that exert different functions than monomers. The pharmacological potential of such complexes is hampered by the limited information available on the type of complex formed and its quaternary structure. Several GPCR structures in the Protein Data Bank display Several GPCR structures in the Protein Data Bank display crystallographic interfaces potentially compatible with physiological interactions that can be employed to generate models. Here we present DIMERBOW, a database and web application aimed to visually browse the complete repertoire of potential GPCR dimers present in solved structures. The tool is suited to help finding the best possible structural template to model GPCR homomers. DIMERBOW is available at http://lmc.uab.es/dimerbow/.
