Abstract: Phosphorylation of G protein-coupled receptors (GPCRs) is one of the most prominent post-translation modifications mediated by agonist stimulation. This process has been shown to result not only in receptor desensitisation but also, via the recruitment of arrestin adaptor proteins, to promote receptor coupling to numerous signalling pathways. Furthermore, there is now a growing body of evidence suggesting that GPCRs may employ phosphorylation as a mechanism to regulate their cell-type-specific signalling, hence generating tissue-specific functions. These advances have resulted partly from improved methods used in the determination of phospho-acceptor sites on GPCRs and improved analysis of the consequences of phosphorylation. This chapter aims to describe the methods used in our laboratory for the investigation of site-specific phosphorylation of the M₃-muscarinic receptor. These methods could easily be applied in the study of other receptors.
