KIR2.3 Polyclonal Antibody

domain:The Val/Gly/Ala/Pro stretch may have a functional role in the conductance or permeation properties.,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.,similarity:Belongs to the inward rectifier-type potassium channel family.,subunit:Homomultimeric and heteromultimeric association with Kir2.1, resulting in an enhanced G-protein-induced current. Association, via its PDZ-recognition domain, with LIN7A, LIN7B, LIN7C, DLG1, CASK and APBA1 plays a key role in its localization and trafficking.,tissue specificity:Heart, skeletal muscle, and several different brain regions including the hippocampus.,
