靶點詳情

  • 功能：
    Probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues. 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 extracellular barium and cesium.

    1. Report coupling of cardiac Kir2.1 and Kir2.2 subunits with the plasma membrane-bound AKAPs 15 and 79. Cardiac membrane-associated AKAPs are a functionally essential part of the regulatory cascade determining IK1 current function. PMID: 28331977
    2. Moreover, the in vivo study showed that rat-VSMC switched to proliferative phenotypes and that knockdown of Kir2.1 significantly inhibited neointimal formation after rat carotid injury. Kir2.1 may be a potential therapeutic target in the treatment of cardiovascular diseases, such as atherosclerosis and restenosis following percutaneous coronary intervention. PMID: 27387235
    3. Th1 response regulates Kir2.1 expression in infarcted hearts and valsartan regulates Th1 response to improve cardiac ion channel remodeling following myocardial infarction. PMID: 26566151
    4. Kir2 channels composed of Kir2.1-2.3 subunits are expressed in neuronal and glial cells in the DRG and spinal cord, contributing to sensory transduction and motor control. PMID: 26854211
    5. Immunohistochemical analysis reveals the expression of Kir2.1, Kir2.2, and Kir2.3 within spontaneously bursting neurons that regulate the level of pacemaker activity within the developing superficial dorsal horn. PMID: 23426663
    6. The inward rectifier potassium current was clearly inhibited after the inhibition of KCNJ2 gene expression by RNA interference. PMID: 22426100
    7. Vascular smooth muscle Kir2.1 channels are involved in the nitroprusside-induced dilation of rat-tail small arteries. PMID: 14993195
    8. In PCR analyses using isolated juxtaglomerular cells, the mRNA for Kir2.1 (Kcnj2) and Kir2.2 (Kcnj12) was detected. Kir2.1 is the dominant component of the channel. PMID: 15284349
    9. The expression of Kir4.1 mRNA was reduced by 55% after ischemia while the expression of Kir2.1 mRNA was not altered. PMID: 16330144
    10. Immunochemical staining verified that both pericytes and endothelial cells of descending vasa recta express K(IR)2.1, K(IR)2.2, and K(IR)2.3 subunits. PMID: 17670900
    11. In addition, LV-mediated overexpression of Kir2.1 opens up the prospect of studying the functional role of inward rectifier K(+) current in cardiac arrhythmias. PMID: 17675572
    12. Biophysical properties of K(IR) (comprised K(IR)2.1 and 2.2 subunits) have a substantive role in enabling agonists to alter the electrical state of a multilayered artery. PMID: 18063660
    13. Experiments demonstrated surface expression of Kir2.1-containing channels in astrocytes and in populations of pyramidal and nonpyramidal cells. Findings for astrocytes were not consistent with predictions for spatial buffering over substantial distance. PMID: 18076085
