靶點詳情

功能：

This potassium channel is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. This receptor plays a crucial role in regulating the heartbeat.

4. K(IR)3.1 channels play a primary role in the antinociceptive effects of oxycodone, but not those of morphine, at supraspinal sites and suggest that supraspinal K(IR)3.1 channels are responsible for the unique analgesic profile of oxycodone. PMID: 24117458
5. siRNA knock-down of NgR1 resulted in a selective increase of GABAB R1 and GABAB R2 protein and an increase in GIRK1. PMID: 23829864

12. Data suggest HL-1 cells express GIRK1/4 and M2 muscarinic receptors and are a good model to study acetylcholine-activated potassium currents. PMID: 20186548
13. confers properties to I(KACh) that enhance channel activity and that Kir3.4 homomultimers do not contribute significantly to the muscarinic-gated potassium current PMID: 12374786
14. Kcnj3 is associated with idiopathic generalised epilepsy syndromes by genotype. PMID: 12458027
15. A cytoplasmic pore in the GIRK1 channel extends the ion pathway to 60 A, nearly twice the length of a canonical transmembrane K(+) channel. The cytoplasmic pore is lined by acidic and hydrophobic amino acids; polyamines block this pore. PMID: 12507423
16. We found GIRK1 and GIRK2 subunits in the spinal cord dorsal horn; GIRK1 and GIRK2 knock-out mice exhibited hyperalgesia. Furthermore GIRK1 and GIRK2 knock-out mice showed decreased analgesic responses after spinal administration of higher morphine doses PMID: 15028774
