Purification notesPurified from rabbit antiserum by affinity chromatography using epitope specific phosphopeptide. The antibody against non phosphopeptide was removed by chromatography using non phosphopeptide corresponding to the phosphorylation site.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000.
FunctionThis potassium channel 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. This receptor plays a crucial role in regulating the heartbeat.
Sequence similaritiesBelongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family. KCNJ3 subfamily.
