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 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

summary for KCNJ1:
The inward-rectifier potassium channel family (also known as 2-TM channels) include the strong
inward-rectifier channels (KIR2.x), the G-protein-activated inward-rectifier channels (KIR3.x) and the
ATP-sensitive channels (KIR6.x, which combine with sulphonylurea receptors (SUR)). Structurally, the
pore-forming subunit of KIR channels is the alpha-subunit. It contains a single pore domain between two
membrane spanning regions. Four alpha-subunits combine to form a tetramer, with the pore domain of each
subunit contributing to the structure of the central pore. Heteromeric channels can also be formed within
subfamilies, e.g. KIR3.2 with KIR3.3.

  • 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
