The epithelial sodium (Na ) channel (ENaC) plays a critical role in blood pressure regulation by controlling renal salt and water reabsorption. Channel overactivity can lead to severe hypertension and underactivity to salt wasting and hypotension.1 In addition to their role in salt/water homeostasis, recent studies suggest that ENaC proteins, and their relatives, the acid-sensing ion channel (A...
Tarantula toxins that bind to voltage-sensing domains of voltage-activated ion channels are thought to partition into the membrane and bind to the channel within the bilayer. While no structures of a voltage-sensor toxin bound to a channel have been solved, a structural homolog, psalmotoxin (PcTx1), was recently crystalized in complex with the extracellular domain of an acid sensing ion channel...
Incorporation of noncanonical amino acids (ncAAs) can endow proteins with novel functionalities, such as crosslinking or fluorescence. In ion channels, the function these variants be studied great precision using standard electrophysiology, but this approach is typically labor intensive and low throughput. Here, we establish a high-throughput protocol to conduct functional pharmacological inves...
The brain liver intestine Na(+) channel (BLINaC) is a member of the degenerin/epithelial Na(+) channel gene family of unknown function. Elucidation of the physiological function of BLINaC would benefit greatly from pharmacological tools that specifically affect BLINaC activity. Guided by the close molecular relation of BLINaC to acid-sensing ion channels, we discovered in this study that rat BL...
PURPOSE Changes in extracellular pH occur in the retina and directly affect retinal activity and phototransduction. The authors analyzed the expression in rodent retina of ASIC3, a sensor of extracellular acidosis, and used ASIC3 knockout mice to explore its role in retinal function and survival. METHODS The expression and the role of ASIC3 were examined by immunolocalization and by comparing...
