Web10 Oct 2024 · Our recent experimental work has revealed unusual features of the effect of ethanol and nicotine on cardiac ionic membrane channels responsible for inwardly rectifying potassium currents ( IKir ); both drugs exhibited inhibition … WebHuman inward rectifier potassium channels in chronic and postoperative atrial fibrillation Human inward rectifier potassium channels in chronic and postoperative atrial fibrillation … Inward-rectifier potassium channels (Kir, IRK) are a specific lipid-gated subset of potassium channels. To date, seven subfamilies have been identified in various mammalian cell types, plants, and bacteria. They are activated by phosphatidylinositol 4,5-bisphosphate (PIP2). The malfunction of … See more A channel that is "inwardly-rectifying" is one that passes current (positive charge) more easily in the inward direction (into the cell) than in the outward direction (out of the cell). It is thought that this current may play an … See more The phenomenon of inward rectification of Kir channels is the result of high-affinity block by endogenous polyamines, namely spermine, as well as magnesium ions, that plug the channel pore at positive potentials, resulting in a decrease in outward currents. This … See more Voltage-dependence may be regulated by external K , by internal Mg , by internal ATP and/or by G-proteins. The P domains of IRK channels exhibit … See more There are seven subfamilies of Kir channels, denoted as Kir1 - Kir7. Each subfamily has multiple members (i.e. Kir2.1, Kir2.2, Kir2.3, … See more All Kir channels require phosphatidylinositol 4,5-bisphosphate (PIP2) for activation. PIP2 binds to and directly activates Kir … See more Kir channels are found in multiple cell types, including macrophages, cardiac and kidney cells, leukocytes, neurons, and endothelial cells. By … See more The crystal structure and function of bacterial members of the IRK-C family have been determined. KirBac1.1, from Burkholderia pseudomallei, is 333 amino acyl residues (aas) long with two N-terminal TMSs flanking a P-loop (residues 1-150), and the C … See more navy and relief society
