The volume-sensitive chloride current (I(ClVol)) exhibit a time-dependent decay presumably due to channel inactivation. In this work, we studied the effects of chloride ions (Cl(-)) and H(+) ions on I(ClVol) decay recorded in HEK-293 and HL-60 cells

We measured unidirectional K+ in- and efflux through an inward rectifier K channel (IRK1) expressed in Xenopus oocytes. The ratio of these unidirectional fluxes differed significantly from expectations based on independent ion movement. In an extrace

We have investigated some of the permeation properties of the pore in Shaker K channels. We determined the apparent permeability ratio of K+, Rb+, and NH4+ ions and block of the pore by external Cs+ ions. Shaker channels were expressed with the bacul

The participation of an extracellular loop in C-type inactivation of voltage-gated K+ channels was investigated. A wild-type phenylalanine (at position 425) between the fifth putative transmembrane segment (S5) and the pore region of the Shaker K+ ch
