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 ion transport. Predicted to be located in T-tubule; dendrite; and neuronal cell body. Predicted to be intrinsic component of membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and limb segment. Orthologous to several human genes including KCNJ12 (potassium inwardly rectifying channel subfamily J member 12). [provided by Alliance of Genome Resources, Apr 2022]
