Predicted to enable neurotransmitter transmembrane transporter activity and nucleoside transmembrane transporter activity. Predicted to be involved in several processes, including nucleoside transport; protein localization to cell surface; and purine nucleobase transmembrane transport. Predicted to be located in coated vesicle; plasma membrane; and vesicle membrane. Predicted to be integral component of plasma membrane. Orthologous to human SLC28A2 (solute carrier family 28 member 2). [provided by Alliance of Genome Resources, Apr 2022]
