Most polarized epithelia constrain solute diffusion between luminal and interstitial compartments using tight junctions and generate mechanical strength using adherens junctions. These intercellular junctions are typically portrayed as incongruent macromolecular complexes with distinct protein components. Herein, we delineate the molecular composition and subdomain architecture of an intercellu...
Protein kinases play an important role in the regulation of epithelial tight junctions. In the present study, we investigated the role of PKCζ (protein kinase Cζ) in tight junction regulation in Caco-2 and MDCK (Madin-Darby canine kidney) cell monolayers. Inhibition of PKCζ by a specific PKCζ pseudosubstrate peptide results in redistribution of occludin and ZO-1 (zona occludens 1) from the inte...
The effects of tight junction structure on water and solute fluxes across proximal tubular epithelium were examined with fiber-matrix equations previously derived by Curry and Michel (1980. Microvascular Research. 20:96-99). Using plausible estimates of tight junction fiber length and width the model predicts solute (Ps) and water permeability (Lp) coefficients that agree with the measured valu...
