Abstract:
Chemokine receptors, which belong to the G protein-coupled receptor (GPCR) family of proteins, are critical regulators of cell migration in the context of immune surveillance, inflammation, and development. Recently determined structures of chemokine receptor CXCR4 reveal unique structural features, and offer templates for homology modeling of other chemokine receptors, which deepen our understanding in ligand-binding modes and signal transduction mechanisms. Dimerization, another intriguing issue for GPCR research, is also reviewed based on all published GPCR structures.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Receptor Downregulation in MVBs
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR activation may...

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...
