This collection explores up-to-date descriptions of known G protein-coupled receptor kinase (GRK)-dependent mechanisms, both associated with G protein-coupled receptor (GPCR) functions and the receptor-independent. The chapters cover a wide range of studies from invertebrates to humans, with sections of the volume covering GRK structure, mechanisms of activation, and interaction with GPCRs, GRKs in cell signaling, as well as physiological and pathophysiological mechanisms regulated by GRKs.  Written for the Methods in Pharmacology and Toxicology series, this book features the kind of practical detail necessary for success in the laboratory.
