Claudin-4 (Clostridium perfringens enterotoxin receptor) is a tight junction protein encoded by the gene CLDN4. Expression of Claudin-4 varies in utility depending on the type of cancer.15
Claudins and Cancer: Promising Proteins for Detection and Diagnosis Claudin family proteins are transmembrane proteins that serve as major cell adhesion molecules of tight junctions. “Tight junctions restrict the flow of ions and aqueous molecules between cells, and their permeability is determined by the profile of claudin expression and arrangement of claudins […]
