Inwardly rectifying potassium channels
Current Opinion in Cell Biology, 1999 Inwardly rectifying potassium (Kir) channels regulate the resting membrane potential of the cell and thereby modulate the electrical activity of cardiac and neuronal cells, insulin secretion and epithelial K(+) transport. Considerable progress in understanding the molecular structure of Kir channels and the way in which they are regulated by ...

Transmembrane Structure of an Inwardly Rectifying Potassium Channel [PDF]
Cell, 1999 Inwardly rectifying potassium channels (K(ir)), comprising four subunits each with two transmembrane domains, M1 and M2, regulate many important physiological processes. We employed a yeast genetic screen to identify functional channels from libraries of K(ir) 2.1 containing mutagenized M1 or M2 domains.

The Relevance of GIRK Channels in Heart Function
Membranes, 2022 Among the large number of potassium-channel families implicated in the control of neuronal excitability, G-protein-gated inwardly rectifying potassium channels (GIRK/Kir3) have been found to be a main factor in heart control. These channels are activated
