  • Function

    This receptor 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 extracellular barium and cesium.
  • Tissue specificity

    Heart, skeletal muscle, and several different brain regions including the hippocampus.
  • Sequence similarities

    Belongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family. KCNJ4 subfamily.
  • Domain

    The Val/Gly/Ala/Pro stretch may have a functional role in the conductance or permeation properties.
  • Cellular localization

    Cell membrane. Cytoplasmic vesicle membrane. TAX1BP3 binding promotes dissociation of KCNJ4 from LIN7 famaly members and KCNJ4 internalization.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) of human hippocampus tissue fixed with Bouin's Fixative and paraffin-embedded staining KIR2.3/HIR with ab84822 at 1:1000 for 1 hour at RT. Secondary Antibody: FITC Goat Anti-Mouse (green) at 1:50 for 1 hour at RT.


  • Overlay histogram showing SH-SY5Y cells stained with ab84822 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab84822, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in SH-SY5Y cells fixed with 4% paraformaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
