Enables identical protein binding activity. Predicted to be involved in several processes, including cellular water homeostasis; glycerol transport; and hydrogen peroxide transmembrane transport. Predicted to act upstream of or within endosomal lumen acidification and kidney development. Located in several cellular components, including cell surface; cytosol; and dendrite. Orthologous to human AQP11 (aquaporin 11). [provided by Alliance of Genome Resources, Apr 2022]
