Enables D-glucose transmembrane transporter activity and dehydroascorbic acid transmembrane transporter activity. Involved in dehydroascorbic acid transport and glucose transmembrane transport. Acts upstream of or within cellular response to glucose starvation. Located in several cellular components, including basolateral plasma membrane; female pronucleus; and photoreceptor inner segment. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in brain disease (multiple); carbohydrate metabolic disorder; myelomeningocele; obesity; and type 2 diabetes mellitus. Orthologous to human SLC2A1 (solute carrier family 2 member 1). [provided by Alliance of Genome Resources, Apr 2022]
