Dynamics and functions of tight junctions
WebAbstract. Understanding of tight junctions has evolved from their historical perception as inert solute barriers to recognition of their physiological and biochemical complexity. Many proteins are specifically localized to tight junctions, including cytoplasmic actin-binding proteins and adhesive transmembrane proteins. WebTight junctions are intercellular adhesion complexes in vertebrates that are required for the formation of functional epithelial and endothelial barriers. Their morphological appearance and biochemical composition, that includes large multimeric protein complexes, have long fostered the belief that they are relatively rigid, non-dynamic structures. Recent …
