Predicted to enable outward rectifier potassium channel activity and potassium ion leak channel activity. Predicted to be involved in potassium ion transmembrane transport. Predicted to act upstream of or within monoatomic ion transmembrane transport. Predicted to be located in membrane. Predicted to be active in plasma membrane. Orthologous to human KCNK4 (potassium two pore domain channel subfamily K member 4).
