Predicted to enable calcium-activated potassium channel activity; outward rectifier potassium channel activity; and potassium ion leak channel activity. Predicted to be involved in cellular response to pH; potassium ion export across plasma membrane; and stabilization of membrane potential. Predicted to be located in plasma membrane. Predicted to be integral component of plasma membrane. Human ortholog(s) of this gene implicated in migraine with aura. Orthologous to human KCNK18 (potassium two pore domain channel subfamily K member 18). [provided by Alliance of Genome Resources, Apr 2022]
