Inwardly rectifying k+ channels
Web27 feb. 1998 · The G-protein-regulated, inwardly rectifying K+ (GIRK) channels are critical for functions as diverse as heart rate modulation and neuronal post-synaptic inhibition. GIRK channels are distributed predominantly throughout the heart, brain, and pancreas. In recent years, GIRK channels have received a … WebKir5.1 is an inwardly-rectifying potassium (Kir) channel with high sensitivity to intracellular H+ (pHi) and extracellular K+ concentration [K+]o, and hence provides a link between pHi and [K+]o changes and membrane potential. The intrinsic pHi sensitivity of Kir5.1 suggests a possible role for this channel in the pHi-dependent processes that ...
