Summaries for KCNJ11 Gene

Entrez Gene Summary for KCNJ11 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 and is found associated with the sulfonylurea receptor SUR. Mutations in this gene are a cause of familial persistent hyperinsulinemic hypoglycemia of infancy (PHHI), an autosomal recessive disorder characterized by unregulated insulin secretion. Defects in this gene may also contribute to autosomal dominant non-insulin-dependent diabetes mellitus type II (NIDDM), transient neonatal diabetes mellitus type 3 (TNDM3), and permanent neonatal diabetes mellitus (PNDM). Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene. [provided by RefSeq, Oct 2009]

GeneCards Summary for KCNJ11 Gene

KCNJ11 (Potassium Inwardly Rectifying Channel Subfamily J Member 11) is a Protein Coding gene. Diseases associated with KCNJ11 include Hyperinsulinemic Hypoglycemia, Familial, 2 and Maturity-Onset Diabetes Of The Young, Type 13. Among its related pathways are Type II diabetes mellitus and Antiarrhythmic Pathway, Pharmacodynamics. Gene Ontology (GO) annotations related to this gene include protein C-terminus binding and voltage-gated potassium channel activity. An important paralog of this gene is KCNJ8.

UniProtKB/Swiss-Prot Summary for KCNJ11 Gene

  • This receptor 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 extracellular barium (By similarity). Subunit of ATP-sensitive potassium channels (KATP). Can form cardiac and smooth muscle-type KATP channels with ABCC9. KCNJ11 forms the channel pore while ABCC9 is required for activation and regulation.

Tocris Summary for KCNJ11 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.

  • Familial hyperinsulinemic hypoglycemia 2 (HHF2) [MIM:601820]: Most common cause of persistent hypoglycemia in infancy. Unless early and aggressive intervention is undertaken, brain damage from recurrent episodes of hypoglycemia may occur. {ECO:0000269 PubMed:10204114, ECO:0000269 PubMed:12364426, ECO:0000269 PubMed:15562009, ECO:0000269 PubMed:15579781, ECO:0000269 PubMed:15807877, ECO:0000269 PubMed:15998776, ECO:0000269 PubMed:16332676, ECO:0000269 PubMed:16357843, ECO:0000269 PubMed:18596924, ECO:0000269 PubMed:19357197, ECO:0000269 PubMed:7847376, ECO:0000269 PubMed:8923010}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Diabetes mellitus, permanent neonatal 2 (PNDM2) [MIM:618856]: A form of permanent neonatal diabetes mellitus, a type of diabetes characterized by onset of persistent hyperglycemia within the first six months of life. Initial clinical manifestations include intrauterine growth retardation, hyperglycemia, glycosuria, osmotic polyuria, severe dehydration, and failure to thrive. Some PNDM2 patients may also have developmental delay, muscle weakness, epilepsy and dysmorphic features. PNDM2 transmission pattern is consistent with autosomal dominant inheritance. {ECO:0000269 PubMed:15115830, ECO:0000269 PubMed:15292329, ECO:0000269 PubMed:15448106, ECO:0000269 PubMed:15448107, ECO:0000269 PubMed:15580558, ECO:0000269 PubMed:15583126, ECO:0000269 PubMed:16609879, ECO:0000269 PubMed:16731833, ECO:0000269 PubMed:17213273, ECO:0000269 PubMed:17652641, ECO:0000269 PubMed:17855752, ECO:0000269 PubMed:20022885, ECO:0000269 PubMed:28842488}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Transient neonatal diabetes mellitus 3 (TNDM3) [MIM:610582]: Neonatal diabetes mellitus, defined as insulin-requiring hyperglycemia within the first month of life, is a rare entity. In about half of the neonates, diabetes is transient and resolves at a median age of 3 months, whereas the rest have a permanent form of diabetes. In a significant number of patients with transient neonatal diabetes mellitus, diabetes type 2 appears later in life. The onset and severity of TNDM3 is variable with childhood-onset diabetes, gestational diabetes or adult-onset diabetes described. {ECO:0000269 PubMed:15718250, ECO:0000269 PubMed:15784703}. Note=The disease is caused by variants affecting the gene represented in this entry.
  • Note=Defects in KCNJ11 may contribute to non-insulin-dependent diabetes mellitus (NIDDM), also known as diabetes mellitus type 2.
  • Maturity-onset diabetes of the young 13 (MODY13) [MIM:616329]: A form of diabetes that is characterized by an autosomal dominant mode of inheritance, onset in childhood or early adulthood (usually before 25 years of age), a primary defect in insulin secretion and frequent insulin-independence at the beginning of the disease. {ECO:0000269 PubMed:22701567}. Note=The disease is caused by variants affecting the gene represented in this entry.
