Protein

Sodium/nucleoside cotransporter 2

Gene

Slc28a2

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Sodium-dependent and purine-selective. Exhibits the transport characteristics of the nucleoside transport system cif or N1 subtype (N1/cif) (selective for purine nucleosides and uridine). Accepts purine, analogs of purine nucleosides and uridine, and exhibits high affinity for adenosine.

Enzyme regulationi

Inhibited by formycin B, partially inhibited by purine analog ara-A.
