Voltage dependence of H+ buffering mediated by sodium bicarbonate cotransport expressed in Xenopus oocytes.
The electrogenic sodium bicarbonate cotransporter (NBCe1) is expressed in many epithelial cells and, in the brain, in glial cells. Little is known about the physiological significance of the NBCe1 for proton homeostasis and for other acid/base-coupled transporters in these cells. We have measured the voltage-dependent transport activity of an NBC from human kidney, type hkNBCe1, expressed in oo...
متن کامل[Mg(2+) inhibits ATP-activated current mediated by rat P2X4 receptors expressed in Xenopus oocytes].
To investigate the modulation of Mg(2+) on rat P2X4 receptors and its underlying mechanism, we transcribed cDNA coding for wild-type and mutant P2X4 receptors to cRNA in vitro, injected the cRNA to oocytes of Xenopus laevis using the microinjection technique and revealed the effect of Mg(2+) on ATP-activated currents (I(ATP)) mediated by P2X4 receptors using the two-electrode whole-cell voltage...
متن کامل4-acetoxyscirpendiol of Paecilomyces tenuipes inhibits Na(+)/D-glucose cotransporter expressed in Xenopus laevis oocytes.
Cordyceps, an entomopathogenic fungus, contains many health-promoting ingredients. Recent reports indicate that the consumption of cordyceps helps reduce blood-sugar content in diabetics. However, the mechanism underlying this reduction in circulatory sugar content is not fully understood. Methanolic extracts were prepared from the fruiting bodies of Paecilomyces tenuipes, and 4-beta acetoxysci...
متن کاملFunctional characterization of NBC4: a new electrogenic sodium-bicarbonate cotransporter.
Sodium-bicarbonate cotransporters are homologous membrane proteins mediating the electrogenic or electroneutral transport of sodium and bicarbonate. Of the functionally characterized sodium-bicarbonate cotransporters (NBC), NBC1 proteins are known to be electrogenic. Here we report the cloning and functional characterization of NBC4c, a new splice variant of the NBC4 gene. At the amino acid lev...
متن کاملThe sodium bicarbonate cotransporter: structure, function, and regulation.
The role of the Na(+)-coupled HCO(3)(-) transporter (NBC) family is indispensable in acid-base homeostasis. Almost all tissues express a member of the NBC family. NBC has been studied extensively in the kidney and plays a role in proximal tubule HCO(3)(-) reabsorption. Although the exact function of this transporter family on other tissues is not very clear, the ubiquitous expression of NBC fam...
