Inwardly rectifying potassium
Un courant potassique rectifiant entrant, (en anglais Inwardly Rectifying K current ou IKIR), est un courant causé par un canal ionique spécifique au potassium. Au potentiel de repos, le mouvement de ces ions est paradoxalement dans le sens sortant dans ce type de canal, depuis l'intérieur vers l'extérieur puisque le potentiel d'équilibre des ions de potassium (Ek) est plus négatif que le potentiel de repos . Cependant, en dessous des valeurs de repos, le mouvement des ions se fai… http://www.hfnl.ustc.edu.cn/detail?id=17148

The protein encoded by this gene is an integral … WebThe encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. It may associate with two other G-protein-activated potassium channels to form a heteromultimeric pore-forming complex. [provided by RefSeq, Jul 2008]. Subcellular location: Extracellular
