Function
Mediates both influx and efflux of nucleosides across the membrane (equilibrative transporter). It is sensitive (ES) to low concentrations of the inhibitor nitrobenzylmercaptopurine riboside (NBMPR) and is sodium-independent. It has a higher affinity for adenosine. Inhibited by dipyridamole and dilazep (anticancer chemotherapeutics drugs).
These data suggest that inhibition of CK2-mediated phosphorylation at Ser254 had the same effect on transporter function as the actual loss of Ser254 in mENT1a, implying that this site is constitutively phosphorylated by CK2.
