Facts about Y+L amino acid transporter 1.
Plays a role in nitric oxide synthesis in human umbilical vein endothelial cells (HUVECs) via transport of L-arginine. Involved in the transport of L- arginine in monocytes.

Highest expression in kidney and peripheral blood leukocytes. Weaker expression is observed in lung, heart, placenta, spleen, testis and small intestine. Expressed in normal fibroblasts and those from LPI patients. Also expressed in HUVECs, monocytes, retinal pigment epithelial cells, and various carcinoma cell lines, with highest expression in a colon-carcinoma cell line.
