Functions
nucleoside transmembrane transporter activity
Processes
cell proliferation / nucleobase-containing compound metabolic process / nucleoside transmembrane transport / nucleoside transport / transmembrane transport
Components
basolateral plasma membrane / integral component of plasma membrane / nuclear membrane / nucleolus / plasma membrane
General Function
Nucleoside transmembrane transporter activity
Specific Function
Mediates equilibrative transport of purine, pyrimidine nucleosides and the purine base hypoxanthine. Very less sensitive than SLC29A1 to inhibition by nitrobenzylthioinosine (NBMPR), dipyridamole, dilazep and draflazine.
