Predicted to enable inward rectifier potassium channel activity. Predicted to be involved in several processes, including potassium ion import across plasma membrane; regulation of pH; and response to carbon dioxide. Predicted to act upstream of or within ion transport. Located in plasma membrane. Is expressed in floor plate; heart; and metanephros. Orthologous to human KCNJ16 (potassium inwardly rectifying channel subfamily J member 16). [provided by Alliance of Genome Resources, Apr 2022]
