Transmission electron micrograph of a section close to the luminal surface of the rat intestinal epithelium showing a tight junction (zonula occludens) extending diagonally across the image from upper...

Transmission electron micrograph of tight junction (zonula occludens) between adjacent plasma membranes in the distal kidney tubule. The darkly staining horizontal structure forms the junctional compl...

Transmission electron micrograph of a tight junction (zonula occludens)between two cells in a section of tissue from a rat thyroid. Image made available by James D. Jamieson and the Department of Cel...

Transmission electron micrograph of two frog epithelial cell cells showing the tight junction complex running horizontally in this image. Additional reference: Farquhar, M.G. and G.E. Palade. 1965. ...

ZO-1 polypeptides lacking the unique-6 (U6) motif are concentrated within disorganized strands on the lateral surface of MDCK cells. MDCK II cells transfected with deltaU6 (A–F) or ZNG (aa1-806) ( (...

The unique-6 (U6) motif of the MAGUK protein, ZO-1, inhibits tight junction localization of GFP fusion proteins containing the SH3-GUK module. Stable MDCK II cell lines expressing GFP fusion proteins ...

Cell expressing delta U6 ZO-1 constructs show novel freeze fracture strands extending onto the lateral membrane. Stable MDCK cell lines were fixed and analyzed by freeze fracture electron microscopy. ...

The unique-5 (U5) and unique-6 (U6) motifs of the MAGUK protein, ZO-1 are required for localization of ZO-1 to the apical tight junction. Cell lines expressing the myc-tagged transgenes ZO1-FL (A and ...

Transmembrane proteins of the tight junction (occludin, claudin-2, JAM-A), but not cytosolic proteins (cingulin, ZO-2, alpha-catenin), are incorporated into the ectopic strands formed by delta-U6 cons...
