Enables potassium channel activity. Predicted to be involved in potassium ion transmembrane transport and stabilization of membrane potential. Predicted to act upstream of or within negative regulation of systemic arterial blood pressure and regulation of resting membrane potential. Predicted to be integral component of plasma membrane. Orthologous to human KCNK6 (potassium two pore domain channel subfamily K member 6). [provided by Alliance of Genome Resources, Apr 2022]
