Background Information

KCNJ1, also called ROMK, is an inward-rectifying K+ channel responsible for basal (non-flow stimulated) K+ secretion. 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. This channel is activated by internal ATP and can be blocked by external barium. The calculated molecule weight is 45kDa, 20953-1-AP can detect the band around 75-80 kDa, it has been considered to be a dimer of KCNJ1.(PMID: 17804670; 7929082; 15767585)
