About This Section Entrez Gene summary for KCNJ1 : Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. It is activated by internal ATP and probably plays an important role in potassium homeostasis. The encoded protein has a greater tendency to allow potassium to flow into a cell rather than out of a cell. Mutations in this gene have been associated with antenatal Bartter syndrome, which is characterized by salt wasting, hypokalemic alkalosis, hypercalciuria, and low blood pressure. Multiple transcript variants encoding different isoforms have been found for this gene. (provided by RefSeq, Jul 2008) UniProtKB/Swiss-Prot: IRK1_HUMAN, P48048 Function : In the kidney, probably plays a major role in potassium homeostasis. Inward rectifier potassium channels arecharacterized 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 summary
for KCNJ1 : The inward-rectifier potassium channel family (also known as 2-TM channels) include the stronginward-rectifier channels (KIR2.x), the G-protein-activated inward-rectifier channels (KIR3.x) and theATP-sensitive channels (KIR6.x, which combine with sulphonylurea receptors (SUR)). Structurally, thepore-forming subunit of KIR channels is the alpha-subunit. It contains a single pore domain between twomembrane spanning regions. Four alpha-subunits combine to form a tetramer, with the pore domain of eachsubunit contributing to the structure of the central pore. Heteromeric channels can also be formed withinsubfamilies, e.g. KIR3.2 with KIR3.3. Gene Wiki entry for KCNJ1 (ROMK)

Defects in KCNJ1 are the cause of Bartter syndrome type 2 (BS2) [MIM:241200]; also termed hyperprostanglandin E syndrome 2. BS refers to a group of autosomal recessive disorders characterized by impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and varying degrees of hypercalciuria. BS2 is a life-threatening condition beginning in utero, with marked fetal polyuria that leads to polyhydramnios and premature delivery. Another hallmark of BS2 is a marked hypercalciuria and, as a secondary consequence, the development of nephrocalcinosis and osteopenia 18 diseases for KCNJ1 : About MalaCards hypercalciuria bartter syndrome, type 2 pseudohypoaldosteronism type ii pseudohypoaldosteronism gitelman syndrome nephrocalcinosis hypokalemia bartter disease cystic fibrosis polyhydramnios hyperaldosteronism essential hypertension nephrolithiasis fibrosis aldosteronism hypertension pancreatitis neuronitis 7 diseases from the University of Copenhagen DISEASES database for KCNJ1 :Bartter disease Gitelman syndrome Pseudohypoaldosteronism Hypokalemia Polyhydramnios Nephrocalcinosis Hyperaldosteronism 10/16 Novoseek disease relationships for KCNJ1 gene (see all 16 ) About this table
