Tight junction protein ZO-1 is a protein that in humans is encoded by the TJP1 gene.[1]

This gene encodes a protein located on a cytoplasmic membrane surface of intercellular tight junctions. The encoded protein may be involved in signal transduction at cell–cell junctions. Two transcript variants encoding distinct isoforms have been identified for this gene.[2]
