Predicted to enable potassium:proton antiporter activity and sodium:proton antiporter activity. Predicted to be involved in potassium ion transmembrane transport; regulation of intracellular pH; and sodium ion import across plasma membrane. Predicted to act upstream of or within several processes, including brain-derived neurotrophic factor receptor signaling pathway; neuron projection development; and regulation of neurotrophin TRK receptor signaling pathway. Predicted to be located in several cellular components, including axon; endoplasmic reticulum membrane; and endosome. Predicted to be active in plasma membrane and recycling endosome. Human ortholog(s) of this gene implicated in Christianson syndrome. Orthologous to human SLC9A6 (solute carrier family 9 member A6). [provided by Alliance of Genome Resources, Apr 2022]
