Claudin-18: A Therapeutic Target in Oncology
Claudins, a family of small tetraspan proteins expressed in a tissue or cell-specific manner, are major components of the multimeric protein architecture of tight junctions, which prevent ions or small molecules from passing freely between epithelial or endothelial cells. These proteins contain four transmembrane domains mainly responsible for interacting side-to-side with neighboring proteins. Two extracellular loops regulate p...
