|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||KCNJ1 / ROMK Antibody (internal region) is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||In the kidney, probably plays a major role in potassium homeostasis. 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. This channel is activated by internal ATP and can be blocked by external barium.|
|Cellular Location||Cell membrane; Multi-pass membrane protein Note=Phosphorylation at Ser-44 by SGK1 is necessary for its expression at the cell membrane|
|Tissue Location||In the kidney and pancreatic islets. Lower levels in skeletal muscle, pancreas, spleen, brain, heart and liver.|
