Polyclonal Rabbit Affinity Purified B IH IF
The tight junction is a cell-to-cell adhesion structure in epithelial cells that constitute the epithelial junctional complex with adherens junctions and desmosomes. Tight junctions seal cells to create a primary barrier to the diffusion of solutes across the cellular sheet and also function as a boundary between the apical and basolateral membrane domains to produce their polarization.1 Tight junction strands are mainly composed of claudins, occludin, and JAM.2 Various scaffold proteins have been reported to be concentrated at the cytoplasmic surfaces of the junctional complex regions to determine the specialization and localization of junctions: ZO-1, ZO-2, and ZO-3. The zona occludins (ZO) proteins constitute the plaque structures underlying plasma membranes together with various proteins including cingulin, symplekin, Par-3·Par-6·atypical protein kinase C complex, ZONAB, and guanine nucleotide exchange factor-H1/Lfc.2 All three ZO proteins have three PDZ domains, one Src homology 3 domain, and one guanylate kinase-like homologue domain in this order from their NH2 termini, indicating that ZO-1, ZO-2, and ZO-3 are membrane-associated guanylate kinase-like homologues (MAGUKs).
