Enables chloride-activated potassium channel activity. Involved in potassium ion export across plasma membrane. Acts upstream of or within potassium ion transport. Predicted to be active in plasma membrane. Predicted to be integral component of membrane. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 57. Orthologous to human KCNT2 (potassium sodium-activated channel subfamily T member 2). [provided by Alliance of Genome Resources, Apr 2022]
