Claudin 7 monoclonal antibody

The Claudin superfamily consists of many structurally related proteins in humans . These proteins are important structural and functional components of tight junctions in paracellular transport . Claudins are located in both epithelial and endothelial cells in all tight junction-bearing tissues . Three classes of proteins are known to localize to tight junctions, including the Claudins, Occludin and Junction adhesion molecule . Claudins, which consist of four transmembrane domains and two extracellular loops make up tight junction strands . Claudin expression is highly restricted to specfic regions of different tissues and may have an important role in transcellular transport through tight junctions . mRNA studies indicate that Claudin-7 is specifically expressed in mouse lung and kidney, but not in heart, brain, spleen, liver, skeletal muscle or testis . The gene encoding human Claudin-7 maps to chromosome 17p13 .
