Entrez Gene summary for KCNJ8 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. Defects in this gene may be a cause of J-wave syndromes and sudden infant
death syndrome (SIDS). (provided by RefSeq, May 2012)

GeneCards Summary for KCNJ8 Gene:
KCNJ8 (potassium inwardly-rectifying channel, subfamily J, member 8) is a protein-coding gene. Diseases associated with KCNJ8 include prinzmetal's variant angina, and sudden infant death syndrome. GO annotations related to this gene include inward rectifier potassium channel activity and ATP-activated inward rectifier potassium channel activity. An important paralog of this gene is KCNJ4.

UniProtKB/Swiss-Prot: IRK8_HUMAN, Q15842
Function: 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 (By similarity)

summary for KCNJ8 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 (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.

    UniProtKB/Swiss-Prot: IRK8_HUMAN, Q15842
  • Note=Defects in KCNJ8 may be associated with susceptibility to J-wave syndromes, a group of heart
    disorders characterized by early repolarization events as indicated by abnormal J-wave manifestation on
    electrocardiogram (ECG). The J point denotes the junction of the QRS complex and the ST segment on the ECG,
    marking the end of depolarization and the beginning of repolarization. An abnormal J wave is a deflection with a
    dome or hump morphology immediately following the QRS complex of the surface ECG. Examples of J-wave disorders
    are arrhythmias associated with an early repolarization pattern in the inferior or mid to lateral precordial
    leads, Brugada syndrome, some cases of idiopathic ventricular fibrillation (VF) with an early repolarization
    pattern in the inferior, inferolateral or global leads, as well as arrhythmias associated with hypothermia
  • Sudden infant death syndrome (SIDS) [MIM:272120]: SIDS is the sudden death of an infant younger than 1
    year that remains unexplained after a thorough case investigation, including performance of a complete autopsy,
    examination of the death scene, and review of clinical history. Pathophysiologic mechanisms for SIDS may include
    respiratory dysfunction, cardiac dysrhythmias, cardiorespiratory instability, and inborn errors of metabolism,
    but definitive pathogenic mechanisms precipitating an infant sudden death remain elusive. Note=Disease
    susceptibility is associated with variations affecting the gene represented in this entry
