title: Pharmacological chaperone approaches for rescuing GPCR mutants: Current state, challenges, and screening strategies.
abstract: A substantial number of G-protein coupled receptors (GPCRs) genetic disorders are due to mutations that cause misfolding or dysfunction of the receptor product. Pharmacological chaperoning approaches can rescue such mutant receptors by stabilizing protein conformations that behave similar to the wild type protein. For example, this can be achieved by improving folding efficiency and/or interaction with chaperone proteins. Although efficacy of pharmacological chaperones has been demonstrated in vitro for a variety of GPCRs, translation to clinical use has been limited. In this paper we discuss the history of pharmacological chaperones of GPCR's and other membrane proteins, the challenges in translation to the clinic, and the use of different assays for pharmacological chaperone discovery.
