G protein-coupled receptors (GPCRs) constitute the largest superfamily of cell surface receptors that regulate a variety of cell functions. Over the past few decades great progress has been made in defining the roles of intracellular trafficking in controlling the functionality of the receptors as well as in the development of various human diseases. This volume of Progress in Molecular Biology and Translational Science reviews the recent understanding of GPCR trafficking regulators and molecular mechanisms.
