{wiki=Inward-rectifier_potassium_channel}
Inward-rectifier potassium channels (often abbreviated as Kir channels) are a type of potassium ion channel that allow potassium ions (K⁺) to flow more easily into the cell than out of it. This property of "inward rectification" is primarily due to the channel's gating mechanisms and its unique biophysical properties.
