Predicted to enable glucose 6-phosphate:inorganic phosphate antiporter activity and glucose-6-phosphate transmembrane transporter activity. Acts upstream of or within several processes, including cholesterol homeostasis; glucose-6-phosphate transport; and hemopoiesis. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be integral component of endoplasmic reticulum membrane. Is expressed in several structures, including alimentary system; genitourinary system; liver; nervous system; and spleen. Used to study glycogen storage disease I. Human ortholog(s) of this gene implicated in congenital disorder of glycosylation type II. Orthologous to human SLC37A4 (solute carrier family 37 member 4).
