SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	SN1 is an isoform of the system N Glutamine Transporters which is the principal mediator of glutamine transport in retinal Müller cells and contributes significantly to glutamine uptake in ganglion cells and, hence,
	contributes to the retinal glutamate-glutamine cycle
	plays an important role in the release of glutamine from brain astrocytes and the uptake of glutamine into hepatocytes (Broer 2009)
	involved in glutamine transport in the liver and in pancreatic beta-cells (Broer 2009)
