ZO-3 Antibody

TJP3 (Tight junction protein 3), also called ZO-3 (Zona occludens 3), is a protein that in humans is encoded by the TJP3 gene. TJP3/ZO-3 is a member of the family of membrane-associated guanylate kinase-like proteins (MAGUK) that associate with intracellular junctions (Itoh et al., 1999) . Haskins et al. (1998) showed that recombinant Tjp3 binds in vitro translated Tjp1 and binds directly to the cytoplasmic tail of occludin but no binding was detected between Tjp3 and Tjp2. Roh et al. (2002) determined that Tjp3 interacted with PATJ (INADL) and that both proteins colocalized to tight junctions in vivo. In vitro studies showed that the sixth and eighth PDZ domains of PATJ mediated interaction with the Tjp3 C-terminal domain and with Cldn1, respectively.
