Predicted to enable PDZ domain binding activity and inward rectifier potassium channel activity. Predicted to be involved in potassium ion import across plasma membrane and regulation of ion transmembrane transport. Predicted to act upstream of or within potassium ion transport. Predicted to be located in basolateral plasma membrane; dendrite; and neuronal cell body. Predicted to be active in plasma membrane. Is expressed in several structures, including adrenal gland; alimentary system; epididymis; telencephalon; and thymus. Orthologous to human KCNJ4 (potassium inwardly rectifying channel subfamily J member 4). [provided by Alliance of Genome Resources, Apr 2022]
