SeqProS possible 387-393 PDZ domain-binding motif; this region is predicted to be disordered by AlphaFold (pLDDT <68.5) and NeProc.
Hetero dimer : A9V7E4
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 (By similarity).
