pubmed:abstractText |
Modulation of neuronal excitability by regulation of K+ channels potentially plays a part in short-term memory but has not yet been studied at the molecular level. Regulation of K+ channels by protein phosphorylation and oxygen has been described for various tissues and cell types; regulation of fast-inactivating K+ channels mediating IK(A) currents has not yet been described. Functional expression of cloned mammalian K+ channels has provided a tool for studying their regulation at the molecular level. We report here that fast-inactivating K+ currents mediated by cloned K+ channel subunits derived from mammalian brain expressed in Xenopus oocytes are regulated by the reducing agent glutathione. This type of regulation may have a role in vivo to link metabolism to excitability and to regulate excitability in specific membrane areas of mammalian neurons.
