Also known as DER12
Summary
SLC29A2 (solute carrier family 29 member 2, HGNC:11004) is a protein-coding gene on chromosome 11q13.2, encoding Equilibrative nucleoside transporter 2 (Q14542). Bidirectional uniporter involved in the facilitative transport of nucleosides and nucleobases, and contributes to maintaining their cellular homeostasis.
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]).

Function. Bidirectional uniporter involved in the facilitative transport of nucleosides and nucleobases, and contributes to maintaining their cellular homeostasis. Functions as a Na(+)-independent, passive transporter. Involved in the transport of nucleosides such as inosine, adenosine, uridine, thymidine, cytidine and guanosine. Also able to transport purine nucleobases (hypoxanthine, adenine, guanine) and pyrimidine nucleobases (thymine, uracil). Involved in nucleoside transport at basolateral membrane of kidney cells, allowing liver absorption of nucleoside metabolites. Mediates apical nucleoside uptake into Sertoli cells, thereby regulating the transport of nucleosides in testis across the blood-testis-barrier. Mediates both the influx and efflux of hypoxanthine in skeletal muscle microvascular endothelial cells to control the amount of intracellular hypoxanthine available for xanthine oxidase-mediated ROS production. Non functional nucleoside transporter protein for adenosine or thymidine transport. Does not express on cell membrane.
Subcellular location. Apical cell membrane. Basolateral cell membrane.
Tissue specificity. Highly expressed in skeletal muscle. Expressed in liver, lung, placenta, brain, heart, kidney and ovarian tissues. Expressed in testis at the blood-brain-barrier.
Post-translational modifications. Glycosylated.
Miscellaneous. Transport activity is insensitive to nanomolar concentrations of the inhibitor nitrobenzylmercaptopurine riboside (NBMPR). Inhibited by higher concentrations of NBMPR (1uM-10uM). May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay.
Similarity. Belongs to the SLC29A/ENT transporter (TC 2.A.57) family.
