Ion conduction and selectivity in acid-sensing ion channel 1
The ability of acid-sensing ion channels (ASICs) to discriminate among cations was assessed based on changes in conductance and reversal potential with ion substitution. Human ASIC1a was expressed in Xenopus laevis oocytes, and acid-induced currents were measured using two-electrode voltage clamp. Replacement of extracellular Na(+) with Li(+), K(+), Rb(+), or Cs(+) altered inward conductance an...
متن کاملSensing tension: epithelial sodium channel/acid-sensing ion channel proteins in cardiovascular homeostasis.
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...
متن کاملAcid-sensing ion channel 3 in retinal function and survival.
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...
متن کاملInhibition of human acid-sensing ion channel 1b by zinc.
Acid-sensing ion channel 1b (ASIC1b) is expressed in peripheral sensory neurons and has been implicated in nociception. Understanding the modulation of ASIC1b will provide important insight into how ASIC1b contributes to pain sensation. In our previous study, we showed that zinc, an important modulator of pain sensation, reduces rat ASIC1b current. However, rat ASIC1b shows several important di...
متن کاملPsalmotoxin-1 docking to human acid-sensing ion channel-1.
Acid-sensing ion channel-1 (ASIC-1) is a proton-gated ion channel implicated in nociception and neuronal death during ischemia. Recently the first crystal structure of a chicken ASIC was obtained. Expanding upon this work, homology models of the human ASICs were constructed and evaluated. Energy-minimized structures were tested for validity by in silico docking of the models to psalmotoxin-1, w...
