Enables glucose-6-phosphate transmembrane transporter activity. Involved in several processes, including glucose-6-phosphate transport; response to glucose; and response to nutrient. Located in intracellular membrane-bounded organelle. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type II. Orthologous to human SLC37A4 (solute carrier family 37 member 4). [provided by Alliance of Genome Resources, Apr 2022]
