Subcellular location

Subcellular Location:
Membrane; Multi-pass membrane protein.

Function

Function:
Sodium-dependent and purine-selective transporter. Exhibits the transport characteristics of the nucleoside transport system cif or N1 subtype (N1/cif) (selective for purine nucleosides and uridine). Plays a critical role in specific uptake and salvage of purine nucleosides in kidney and other tissues.
Enzyme Regulation:
ENZYME REGULATION: Inhibited by formycin B.
