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

edit

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]
