Gene: Kcnj1 (potassium inwardly-rectifying channel, subfamily J, member 1) Mus musculus
Symbol: Kcnj1
Name: potassium inwardly-rectifying channel, subfamily J, member 1
Description: Predicted to have several functions, including ATP-activated inward rectifier potassium channel activity; phosphatidylinositol-4,5-bisphosphate binding activity; and potassium ion binding activity. Involved in several processes, including regulation of G-protein activated inward rectifier potassium channel activity; renal sodium ion absorption; and tissue homeostasis. Predicted to localize to the plasma membrane. Used to study Bartter disease type 2. Human ortholog(s) of this gene implicated in Bartter disease type 2. Is expressed in heart and metanephros. Orthologous to human KCNJ1 (potassium inwardly rectifying channel subfamily J member 1); PARTICIPATES IN aldosterone signaling pathway; INTERACTS WITH 1,1-dichloroethene; 1,2-dichloroethane; 2,3,7,8-tetrachlorodibenzodioxine.
Type: protein-coding
RefSeq Status: VALIDATED
Also known as: ATP-regulated potassium channel ROM-K; ATP-sensitive inward rectifier potassium channel 1; inward rectifier K(+) channel Kir1.1; inwardly rectifying potassium channel ROMK-2; Kir1.1; potassium channel, inwardly rectifying subfamily J member 1; ROMK; Romk2
