Enables 5-amino-1-ribofuranosylimidazole-4-carboxamide transmembrane transporter activity and nicotinamide riboside transmembrane transporter activity. Involved in 5-amino-1-ribofuranosylimidazole-4-carboxamide transmembrane transport; nicotinamide riboside transport; and thiamine transport. Predicted to be located in membrane. Predicted to be active in plasma membrane.
SGD Description
High-affinity nicotinamide riboside transporter; also transports thiamine with low affinity; major transporter for 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (acadesine) uptake; shares sequence similarity with Thi7p and Thi72p; proposed to be involved in 5-fluorocytosine sensitivity
