Background: Claudin-8

Claudin-8 is a 225 amino acid (aa), 25 kDa four-transmembrane protein in the Claudin family of tight junction proteins. It is selectively expressed in tight junctions in the kidney thin descending limb, distal tubule and collecting duct, but is also found in liver and intestinal tight junctions. It is thought to function as an ion barrier protein. The extracellular portions of human Claudin-8 share 86% and 89% aa identity with corresponding portions of mouse and rat Claudin-8, respectively.
