The integrin family is a transmembrane receptor that plays critical roles in the cell-cell and cell-extracellular matrix adhesion, signal transduction such as cell cycle regulation, organization of the intracellular cytoskeleton, and immune responses. Consequently, dysfunction of integrins is associated with a wide range of human diseases, including cancer and immune diseases, which makes integrins therapeutic targets for drug discovery. Here we report the cryo-EM structure of the human α-I domain-containing full-length integrin αEβ7, which is expressed in the leukocytes of the immune system and a drug target for inflammatory bowel disease (IBD). The structure reveals the half-bent conformation, an intermediate between the close and the open conformation, while the α-I domain responsible for the ligand binding covers the headpiece domain by a unique spatial arrangement. Our results provide the structural information for the drug design targeting IBD.
