Background

ZO-1 (also known as TJP1) is a peripheral membrane phosphoprotein with a molecular mass of 220 kDa, located on the cytoplasmic face and is expressed in tight junctions of both epithelial and endothelial cells. (1) Two isoforms, ZO-1α− and ZO-1α+, have been described, which, as a result of alternative RNA splicing, differ by an internal 80 amino acid sequence. (2) 
ZO-1 binds the transmembrane proteins occludin and the claudins linking them to cytoskeletal actin. (3)
