NCBI Summary for ROMK/Kir1.1
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]
UniProt Comments for ROMK/Kir1.1
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.

Enzyme regulation: Inhibited by WNK3. Ref.10

Subunit structure: Interacts with SGK1 and SLC9A3R2/NHERF2. Ref.8

Subcellular location: Cell membrane; Multi-pass membrane protein. Note: Phosphorylation at Ser-44 by SGK1 is necessary for its expression at the cell membrane. Ref.9

Tissue specificity: In the kidney and pancreatic islets. Lower levels in skeletal muscle, pancreas, spleen, brain, heart and liver. Ref.6

Post-translational modification: Phosphorylation at Ser-44 by SGK1 is necessary for its expression at the cell membrane.

Involvement in disease: Bartter syndrome 2 (BS2) [MIM:241200]: An autosomal recessive disorder characterized by impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and varying degrees of hypercalciuria. Bartter syndrome type 2 is a life-threatening condition beginning in utero, with marked fetal polyuria that leads to polyhydramnios and premature delivery. Another hallmark is a marked hypercalciuria and, as a secondary consequence, the development of nephrocalcinosis and osteopenia.Note: The disease is caused by mutations affecting the gene represented in this entry. Ref.11 Ref.12 Ref.13

Sequence similarities: Belongs to the inward rectifier-type potassium channel (TC 1.A.2.1) family. KCNJ1 subfamily. [View classification]
