19380585-2	2009	Na(+)-coupled hCNT1 and hCNT2 transport pyrimidine and purine nucleosides, respectively, whereas hCNT3 mediates transport of both pyrimidine and purine nucleosides utilizing Na(+) and/or H(+) electrochemical gradients.	Purine Nucleosides	55-73	solute carrier family 28 member 1	Homo sapiens	14-19	
12856181-2	2004	These subtypes differ in their substrate specificities: CNT1 is pyrimidine-nucleoside preferring, CNT2 is purine-nucleoside preferring, and CNT3 transports both pyrimidine and purine nucleosides.	Purine Nucleosides	106-123	solute carrier family 28 member 1	Homo sapiens	56-60	
12856181-2	2004	These subtypes differ in their substrate specificities: CNT1 is pyrimidine-nucleoside preferring, CNT2 is purine-nucleoside preferring, and CNT3 transports both pyrimidine and purine nucleosides.	Purine Nucleosides	176-194	solute carrier family 28 member 1	Homo sapiens	56-60	
12055084-1	2002	The human concentrative (Na+-linked) plasma membrane transport proteins hCNT1, hCNT2, and hCNT3 are pyrimidine nucleoside-selective (system cit), purine nucleoside-selective (system cif), or broadly selective for both pyrimidine and purine nucleosides (system cib), respectively.	Purine Nucleosides	146-163	solute carrier family 28 member 1	Homo sapiens	72-77

28385889-2	2017	Na+-coupled hCNT1 and hCNT2 transport pyrimidine and purine nucleosides, respectively, whereas hCNT3 transports both pyrimidine and purine nucleosides utilizing Na+ and/or H+ electrochemical gradients.	Purine Nucleosides	132-150	solute carrier family 28 member 1	Homo sapiens	12-17	
10455109-0	1999	Identification of amino acid residues responsible for the pyrimidine and purine nucleoside specificities of human concentrative Na(+) nucleoside cotransporters hCNT1 and hCNT2.	Purine Nucleosides	73-90	solute carrier family 28 member 1	Homo sapiens	160-165	
10087507-1	1998	Two Na(+)-dependent nucleoside transporters implicated in adenosine and uridine transport in mammalian cells are distinguished functionally on the basis of substrate specificity: CNT1 is selective for pyrimidine nucleosides but also transports adenosine; CNT2 (also termed SPNT) is selective for purine nucleosides but also transports uridine.	Purine Nucleosides	296-314	solute carrier family 28 member 1	Homo sapiens	179-183
