Inwardly rectifying meaning
WebDefinition of inward rectification These channels are termed inwardly rectifying - because they rectify current in the inward direction. This means that under equal but opposite electrochemical potentials, these channels will pass more inward current than they do outward, as in figure 1. WebG protein-gated inwardly rectifying K+ (GIRK/Kir3) channels are critical mediators of excitability in the heart and brain. Enhanced GIRK channel activity has been implicated in the pathogenesis of supraventricular arrhythmias, including atrial fibrillation. The lack of selective pharmacol …
