    Summary
    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 be located in membrane. Predicted to be active in plasma membrane. Is expressed in intestine; muscle cell; and neurons. Orthologous to human KCNK2 (potassium two pore domain channel subfamily K member 2). [provided by Alliance of Genome Resources, Dec 2024]
