Conceptual barriers to understanding physical barriers [PDF]

open access: yesSeminars in Cell & Developmental Biology, 2015
The members of the large family of claudin proteins regulate ion and water flux across the tight junction. Many claudins, e.g. claudins 2 and 15, accomplish this by forming size- and charge-selective paracellular channels. Claudins also appear to be essential for genesis of tight junction strands and recruitment of other proteins to these sites.
