11139404-2	2001	In the present study, we have produced recombinant hENT1, rENT1, hENT2 and rENT2 in Xenopus oocytes and investigated uridine transport following exposure to the impermeant thiol-reactive reagent p-chloromercuriphenyl sulphonate (PCMBS).	Sulfhydryl Compounds	172-177	solute carrier family 29 member 1 (Augustine blood group)	Homo sapiens	51-56	
22837314-2	2012	A previous study from our laboratory established Cys222 in transmembrane (TM) 6 as the residue responsible for methyl methanethiosulfonate (a membrane-permeable sulfhydryl modifier)-mediated enhancement of the binding of the ENT1 inhibitor nitrobenzylmercaptopurine riboside (NBMPR) in intact cells.	Sulfhydryl Compounds	161-171	solute carrier family 29 member 1 (Augustine blood group)	Homo sapiens	225-229	
21791574-2	2011	Given that selective ENT1 inhibitors, such as nitrobenzylmercaptopurine riboside (NBMPR), bind to the N-terminal half of the ENT1 protein, we hypothesized that one or more of the four cysteine residues in this region were contributing to the effects of the sulfhydryl modifiers.
