Regulation of epithelial barrier function requires targeted insertion of tight junction proteins that have distinct selectively permeable characteristics. The insertion of newly synthesized proteins and recycling of internalized tight junction components control both polarity and junction function. Here we show that the small GTPase Rab14 regulates tight junction structure. In Madin-Darby canin...
Claudins are the critical transmembrane proteins in tight junctions. Claudin-5, for instance, prevents paracellular permeation of small molecules. However, the molecular interaction mechanism is unknown. Hence, the claudin-claudin interaction and tight junction strand formation were investigated using systematic single mutations. Claudin-5 mutants transfected into tight junction-free cells demo...
In different epithelia, cell membranes contacting one another form intercellular junctional complexes including tight, adherens and gap junctions, which could mutually influence the expression of each other. We have here investigated the role of Cx43 in the control of adherens and tight junction proteins (N-cadherin, beta-catenin, occludin and ZO-1) by using conditional Sertoli cell knockout Cx...
The tight junction proteins claudins are abnormally regulated in several human cancers. In particular, claudin-3 and claudin4 are frequently overexpressed in several neoplasias, including ovarian, breast, pancreatic, and prostate cancers. Although the exact roles of these proteins in tumorigenesis are still being uncovered, it is clear that they represent promising targets for cancer detection,...
