In humans an additional delta-subunit (delta-hENaC) exists but little is known about its function. Using the Xenopus laevis oocyte expression system, we compared the functional properties of alphabetagamma- and deltabetagamma-hENaC and investigated whether deltabetagamma-hENaC can be proteolytically activated. The amiloride-sensitive ENaC whole-cell current (DeltaI(ami)) was about 11-fold larger in oocytes expressing deltabetagamma-hENaC than in oocytes expressing alphabetagamma-hENaC. The 2-fold larger single-channel Na(+) conductance of deltabetagamma-hENaC cannot explain this difference. Using a chemiluminescence assay, we demonstrated that an increased channel surface expression is also not the cause. Thus, overall channel activity of deltabetagamma-hENaC must be higher than that of alphabetagamma-hENaC. Experiments exploiting the properties of the known betaS520C mutant ENaC confirmed this conclusion. Moreover, chymotrypsin had a reduced stimulatory effect on deltabetagamma-hENaC whole-cell currents compared with its effect on alphabetagamma-hENaC whole-cell currents (2-fold versus 5-fold). This suggests that the cell surface pool of so-called near-silent channels that can be proteolytically activated is smaller for deltabetagamma-hENaC than for alphabetagamma-hENaC. Proteolytic activation of deltabetagamma-hENaC was associated with the appearance of a delta-hENaC cleavage product at the cell surface. Finally, we demonstrated that a short inhibitory 13-mer peptide corresponding to a region of the extracellular loop of human alpha-ENaC inhibited DeltaI(ami) in oocytes expressing alphabetagamma-hENaC but not in those expressing deltabetagamma-hENaC. We conclude that the delta-subunit of ENaC alters proteolytic channel activation and enhances base-line channel activity.}}, author = {{Haerteis, Silke and Krueger, Bettina and Korbmacher, Christoph and Rauh, Robert}}, journal = {{Journal of Biological Chemistry}}, number = {{42}}, pages = {{29024–29040}}, publisher = {{American Society for Biochemistry and Molecular Biology}}, title = {{{The $\delta$-Subunit of the Epithelial Sodium Channel (ENaC) Enhances Channel Activity and Alters Proteolytic ENaC Activation}}}, doi = {{10.1074/jbc.m109.018945}}, volume = {{284}}, year = {{2009}}, } @article{54938, abstract = {{The lipid environment of the epithelial sodium channel (ENaC) and its possible association with so-called lipid rafts may be relevant to its function. The aim of our study was to confirm the association of ENaC with lipid rafts and to analyze the effect of cholesterol depletion of the plasma membrane by methyl-beta-cyclodextrin (MbetaCD) on channel function and regulation. Using sucrose density gradient centrifugation we demonstrated that a significant portion of ENaC protein distributes to low density fractions thought to be typical lipid raft fractions. Importantly, cholesterol depletion of cell lysate by MbetaCD shifted ENaC to non-raft fractions of higher density. Live cell imaging demonstrated that treatment with MbetaCD largely reduced filipin staining over time, confirming cholesterol depletion of the plasma membrane. For electrophysiological studies intact oocytes were exposed to 20 mM MbetaCD for three hours. MbetaCD treatment had no consistent effect on baseline whole-cell ENaC currents. In addition to the typical single channel conductance of about 5 pS, subconductance states of ENaC were occasionally observed in patches from MbetaCD treated but not from control oocytes. Importantly, in outside-out patch clamp recordings the stimulatory effect of recombinant SGK1 in the pipette solution was essentially abolished in oocytes pretreated with MbetaCD. These results indicate that ENaC activation by cytosolic SGK1 is compromised by removing cholesterol from the plasma membrane. Thus, ENaC activation by SGK1 may require the presence of an intact lipid environment and/or of lipid rafts as signalling platform.}}, author = {{Krueger, Bettina and Haerteis, Silke and Yang, Limin and Hartner, Andrea and Rauh, Robert and Korbmacher, Christoph and Diakov, Alexei}}, journal = {{Cellular Physiology and Biochemistry}}, number = {{5-6}}, pages = {{605–618}}, publisher = {{S.
