The SLC37A4 transport protein in the endoplasmic reticulum membrane mediates the exchange of cytosolic G6P (glucose-6-phosphate) and Pi (orthophosphate) from the endoplasmic reticulum lumen. Defects in this transporter are associated with glycogen storage disease type Ib (Gerin et al. 1997; Chen et al. 2008; Veiga-da-Cunha et al. 1998).
