Gene: KCNJ4 (potassium inwardly rectifying channel subfamily J member 4) Homo sapiens
Symbol: KCNJ4
Name: potassium inwardly rectifying channel subfamily J member 4
Description: Exhibits PDZ domain binding activity. Predicted to be involved in potassium ion import across plasma membrane and regulation of ion transmembrane transport. Localizes to basolateral plasma membrane.
Type: protein-coding
RefSeq Status: REVIEWED
