Summaries for KCNJ5 Gene

Entrez Gene Summary for KCNJ5 Gene

  • 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. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, is controlled by G-proteins. It may associate with two other G-protein-activated potassium channels to form a heteromultimeric pore-forming complex. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNJ5 Gene

KCNJ5 (Potassium Voltage-Gated Channel Subfamily J Member 5) is a Protein Coding gene. Diseases associated with KCNJ5 include Hyperaldosteronism, Familial, Type Iii and Long Qt Syndrome 13. Among its related pathways are Transmission across Chemical Synapses and Potassium Channels. GO annotations related to this gene include inward rectifier potassium channel activity and G-protein activated inward rectifier potassium channel activity. An important paralog of this gene is KCNJ6.

UniProtKB/Swiss-Prot for KCNJ5 Gene

  • This 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. Can be blocked by external barium.

Tocris Summary for KCNJ5 Gene

  • 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.

  • Hyperaldosteronism, familial, 3 (HALD3) [MIM:613677]: A form of hyperaldosteronism characterized by hypertension secondary to massive adrenal mineralocorticoid production. HALD3 patients present with childhood hypertension, elevated aldosteronism levels, and high levels of the hybrid steroids 18-oxocortisol and 18-hydroxycortisol. Hypertension and aldosteronism are not reversed by administration of exogenous glucocorticoids and patients require adrenalectomy to control hypertension. {ECO:0000269 PubMed:21311022, ECO:0000269 PubMed:22203740, ECO:0000269 PubMed:22275527, ECO:0000269 PubMed:22308486, ECO:0000269 PubMed:22848660}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Long QT syndrome 13 (LQT13) [MIM:613485]: A heart disorder characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to exercise or emotional stress, and can present with a sentinel event of sudden cardiac death in infancy. {ECO:0000269 PubMed:20560207}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=Somatic mutations in KCNJ5 have been found in aldosterone-producing adrenal adenomas and can be responsible for aldosteronism associated with cell autonomous proliferation. APAs are typically solitary, well circumscribed tumors diagnosed between ages 30 and 70. They come to medical attention due to new or worsening hypertension, often with hypokalemia. The precise role of KCNJ5 mutations in APA is under debate. They produce increased sodium conductance and cell depolarization, which in adrenal glomerulosa cells produces calcium entry, the signal for aldosterone production and cell proliferation. However, they may not be causative of APA development but may be a consequence of tumorigenesis, playing only a contributory role toward aldosterone overproduction and tumor growth (PubMed:22275527). Somatic mutations in KCNJ5 have not been found in non-aldosterone secreting adrenal adenomas suggesting that they are specifically associated with APA (PubMed:22275527 and PubMed:22848660). {ECO:0000269 PubMed:21311022, ECO:0000269 PubMed:22203740, ECO:0000269 PubMed:22275527, ECO:0000269 PubMed:22848660}.
