  • 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. Can be blocked by external barium.
  • 基因功能參考文獻(xiàn)：
    1. Blocking IK,ACh-c by tertiapin significantly decreased DFT, which correlated with a significant increase in wavelength during reentry. Genetic knockdown experiments with Kcnj5-specific shRNA to modulate IK,ACh-c, yielded similar results PMID: 26487066
    2. The KCNJ5 gene and Kir3.4 protein were measured, and acetylcholine-sensitive potassium channel currents were recorded by patch-clamp. PMID: 25696012
    3. localized in intercalated discs in rat ventricle, whereas it was expressed in intercalated discs and outer sarcolemmas in rat atrium PMID: 24148898
    4. the GIRK4 channel protein plays a role in regulating membrane excitability in chemically defined neurons of the arcuate nucleus that control body weight PMID: 22465809
    5. All these findings suggest a new role for the K(ATP) channel as a molecular sensor of atrophy. PMID: 20064856
    6. hydrogen sulfide-induced increase in I(K,ATP) on both atrial and ventricular myocytes was concentration dependent PMID: 19940474
    7. The point mutation L337R in the GIRK4 C terminus decreased the association between the N and C termini. PMID: 15716420
