  • 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.
