18621735-1	2008	In humans, the SLC28 concentrative nucleoside transporter (CNT) protein family is represented by three Na+-coupled members; human CNT1 (hCNT1) and hCNT2 are pyrimidine and purine nucleoside-selective, respectively, whereas hCNT3 transports both purine and pyrimidine nucleosides and nucleoside drugs.	purine	172-178	solute carrier family 28 member 1	Homo sapiens	130-134	
22644860-1	2012	The concentrative nucleoside transporter CNT1 and equilibrated nucleoside transporter ENT1 mediate the cellular uptake of naturally occurring pyrimidine and purine nucleosides and many structurally diverse anticancer and antiviral nucleoside analogs, thereby regulating drug responses or toxicity at the target site.	purine	157-163	solute carrier family 28 member 1	Homo sapiens	41-45
