Tight junction proteins (TJPs) belong to a family of membrane-associated guanylate kinase (MAGUK) homologs that are involved in the organization of epithelial and endothelial intercellular junctions. TJPs bind to the cytoplasmic C termini of junctional transmembrane proteins and link them to the actin cytoskeleton [supplied by OMIM].^[6]

Interactions

Tight junction protein 2 has been shown to interact with tight junction protein 1,^[7][8][9] band 4.1,^[10] occludin^[7][8][11] and USP53.^[12]
