Gene: KCNJ1 (potassium inwardly rectifying channel subfamily J member 1) Homo sapiens
Symbol: KCNJ1
Name: potassium inwardly rectifying channel subfamily J member 1
Description: Exhibits phosphatidylinositol-4,5-bisphosphate binding activity. Predicted to be involved in potassium ion import across plasma membrane. Predicted to localize to the voltage-gated potassium channel complex. Implicated in Bartter disease type 2.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ATP-regulated potassium channel ROM-K; ATP-sensitive inward rectifier potassium channel 1; inward rectifier K(+) channel Kir1.1; inwardly rectifying K+ channel; KIR1.1; potassium channel, inwardly rectifying subfamily J member 1; potassium channel, inwardly rectifying subfamily J, member 1; potassium inwardly-rectifying channel, subfamily J, member 1; potassium voltage-gated channel subfamily J member 1; ROMK; ROMK1
