9435697-3	1997	Functional expression in Xenopus laevis oocytes identified hSPNT1 as a Na(+)-dependent nucleoside transporter that selectively transports purine nucleosides but also transports uridine.	Uridine	177-184	solute carrier family 28 member 2	Homo sapiens	59-65	
9435697-4	1997	The Michaelis constant (K(m)) of uridine (80 microM) in interacting with hSPNT1 was substantially higher than that of inosine (4.5 microM).	Uridine	33-40	solute carrier family 28 member 2	Homo sapiens	73-79
