GPCRomics: An Approach to Discover GPCR Drug Targets

Publication date: Available online 8 May 2019Source: Trends in Pharmacological SciencesAuthor(s): Paul A. Insel, Krishna Sriram, Matthew W. Gorr, Shu Z. Wiley, Alexander Michkov, Cristina Salmerón, Amy M. ChinnG protein-coupled receptors (GPCRs) are targets for ∼35% of approved drugs but only ∼15% of the ∼800 human GPCRs are currently such targets. GPCRomics, the use of unbiased, hypothesis-generating methods [e.g., RNA-sequencing (RNA-seq)], with tissues and cell types to identify and quantify GPCR expression, has led to the discovery of previously unrecognized GPCRs that contribute to functional responses and pathophysiology and that may be therapeutic targets. The combination of GPCR expression data with validation studies (e.g., signaling and functional activities) provides opportunities for the discovery of disease-relevant GPCR targets and therapeutics. Here, we review insights from GPCRomic approaches, gaps in knowledge, and future directions by which GPCRomics can advance GPCR biology and the discovery of new GPCR-targeted drugs.
