Gene: Kcnj2 (potassium inwardly-rectifying channel, subfamily J, member 2) Rattus norvegicus
Symbol: Kcnj2
Name: potassium inwardly-rectifying channel, subfamily J, member 2
CRRD ID: 61968
Description: Predicted to have identical protein binding activity; phosphatidylinositol-4,5-bisphosphate binding activity; and voltage-gated potassium channel activity. Involved in cellular response to mechanical stimulus; positive regulation of potassium ion transmembrane transport; and regulation of cardiac muscle cell contraction. Localizes to several cellular components, including T-tubule; endoplasmic reticulum; and intercalated disc. Used to study myocardial infarction. Human ortholog(s) of this gene implicated in Andersen-Tawil syndrome; familial atrial fibrillation; familial periodic paralysis; and short QT syndrome. Orthologous to human KCNJ2 (potassium inwardly rectifying channel subfamily J member 2); PARTICIPATES IN neuron-to-neuron signaling pathway via the chemical synapse; acebutolol pharmacodynamics pathway; adrenergic beta receptor agonist and beta-blocker pharmacodynamics pathway; INTERACTS WITH 3,3',4,4',5-pentachlorobiphenyl; acetamide; ammonium chloride.
Type: protein-coding
Also known as: inward rectifier K(+) channel Kir2.1; inward rectifier potassium channel 2; IRK-1; Kir2.1; potassium channel, inwardly rectifying subfamily J member 2; potassium channel, inwardly rectifying subfamily J, member 2; potassium voltage-gated channel subfamily J member 2; RBL-IRK1
