Aquaporin 0 enhances gap junction coupling via its cell adhesion function and interaction with connexin 50.
Both connexin 50 (Cx50) and aquaporin 0 (AQP0) have important roles in lens development and homeostasis, and their mutations are associated with human congenital cataracts. We have previously shown that Cx50 directly interacts with AQP0. Here, we demonstrate the importance of the Cx50 intracellular loop (IL) domain in mediating the interaction with AQP0 in the lens in vivo. AQP0 significantly i...
متن کاملAquaporin 0 Modulates Lens Gap Junctions in the Presence of Lens-Specific Beaded Filament Proteins
Purpose The objective of this study was to understand the molecular and physiologic mechanisms behind the lens cataract differences in Aquaporin 0-knockout-Heterozygous (AQP0-Htz) mice developed in C57 and FVB (lacks beaded filaments [BFs]) strains. Methods Lens transparency was studied using dark field light microscopy. Water permeability (Pf) was measured in fiber cell membrane vesicles. We...
متن کاملHeteromeric connexons in lens gap junction channels.
Gap junction channels are formed by paired oligomeric membrane hemichannels called connexons, which are composed of proteins of the connexin family. Experiments with transfected cell lines and paired Xenopus oocytes have demonstrated that heterotypic intercellular channels which are formed by two connexons, each composed of a different connexin, can selectively occur. Studies by Stauffer [Stauf...
متن کاملThe Gap Junction Communication Channel
Communication plays an important role in the rapid Connexin Structure progress of modern society. We live in an age when Gap junctions exhibit a hierarchy of assembly. The prininformation is transmitted through many different pathcipal structural component, the membrane protein conways and in many different forms to influence our daily nexin, is organized into the basic unit of structure, the d...
متن کاملThe C terminus of lens aquaporin 0 interacts with the cytoskeletal proteins filensin and CP49.
PURPOSE Aquaporin 0 (AQP0), the most abundant membrane protein in the lens, is a water-permeable channel, has a role in fiber cell adhesion, and is essential for fiber cell structure and organization. The purpose of this study was to identify proteins that interact with the C terminus of AQP0, by using a proteomics approach, and thus further elucidate the role of AQP0 in the human lens. METHO...
