As a membrane protein, it is difficult to crystalize and its three-dimensional structure is not known until recent years. Thanks to the development of the crystal engineering techniques and the breakthroughs in the free electron X-ray laser crystallography, many crystal structures of β2 adrenergic receptor at different states become available now. The discovery of the crystal struc- ture β2 adrenergic receptor has enriched our understanding on many life phenomena and its im- pact to the structure-based drug design cannot be overestimated. We review the discovery history of β2 adrenergic receptor crystal structures, the structural characteristics of the receptor, the in- teractions between the receptor and different subtypes of the ligands (agonist, inverse agonist and antagonist) and clinical applications.
