The concentrative nucleoside transporter (CNT) (TC 2.A.41) family includes , which is a purine-specific Na+-nucleoside cotransporter localised to the bile canalicular membrane []. It also includes , a Na+-dependent nucleoside transporter selective for pyrimidine nucleosides and adenosine, which also transports the anti-viral nucleoside analogues AZT and ddC [].This domain lies towards the N terminus of this family of transporters.
