Gene: Kcnj2 (potassium inwardly-rectifying channel, subfamily J, member 2) Mus musculus
Symbol: Kcnj2
Name: potassium inwardly-rectifying channel, subfamily J, member 2
Description: Exhibits identical protein binding activity. Involved in cardiac muscle cell action potential and magnesium ion transport. Predicted to localize to several cellular components, including T-tubule; endoplasmic reticulum; and intercalated disc. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and sensory organ. 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 acebutolol pharmacodynamics pathway; adrenergic beta receptor agonist and beta-blocker pharmacodynamics pathway; amiodarone pharmacodynamics pathway; INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 3,4-methylenedioxymethamphetamine; 5-aza-2'-deoxycytidine.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: inward rectifier K(+) channel Kir2.1; inward rectifier potassium channel 2; IRK-1; IRK1; Kcnf1; Kir2.1; potassium channel, inwardly rectifying subfamily J member 2
