WebInward rectifying potassium single-channel currents were studied in the membrane of guinea pig cardiac myocytes. In isolated inside-out patches two differe Inward-rectifying … WebPatch-clamp studies revealed that ABA did not affect the MgC channels but differentially regulated the time-dependent Ksup (+) channels. ABA caused a pronounced rise in time-dependent outward-rectifying Ksup (+) currents (Ksub (out)) at alkaline pH and decreased inward-rectifying Ksup (+) currents (Ksub (in)) in a Casup (2+)-dependent manner.
WebWe conclude that the SPM site responsible for the inward rectifying block is located at electrical distance ~0.5 from the inside and is involved in a flux-coupling segment in the bundle crossing region of the pore. With preponderant outward K+ flow, SPM is “pushed” to the outmost site of this segment (~D172). WebInwardly rectifying K(+) (Kir) channels allow K(+) to move more easily into rather than out of the cell. They have diverse physiological functions depending on their type and their …
