Summaries for SLC29A2 Gene

Entrez Gene Summary for SLC29A2 Gene

  • The uptake of nucleosides by transporters, such as SLC29A2, is essential for nucleotide synthesis by salvage pathways in cells that lack de novo biosynthetic pathways. Nucleoside transport also plays a key role in the regulation of many physiologic processes through its effect on adenosine concentration at the cell surface (Griffiths et al., 1997 [PubMed 9396714]).[supplied by OMIM, Nov 2008]

GeneCards Summary for SLC29A2 Gene

SLC29A2 (Solute Carrier Family 29 Member 2) is a Protein Coding gene. Among its related pathways are Transport of vitamins, nucleosides, and related molecules and Gemcitabine, Pharmacokinetics/Pharmacodynamics Pathway. GO annotations related to this gene include nucleoside transmembrane transporter activity. An important paralog of this gene is SLC29A3.

UniProtKB/Swiss-Prot for SLC29A2 Gene

  • 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.

Tocris Summary for SLC29A2 Gene

  • Nucleoside transporters are divided into two families: the Na+-dependent solute carrier family 28 (SLC28) and the equilibrative solute carrier family 29 (SLC29). SLC28 family transporters (CNT1, 2 and 3) display subtype-selective tissue expression patterns.
