Facts about Y+L amino acid transporter 2.
Also functions as an arginine/glutamine exchanger, after an antiport mechanism for amino acid transport, influencing arginine discharge in exchange for extracellular amino acids. Plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine.
