Gene Information

human ... SLC29A2(3177)

General description

The gene solute carrier family 29 member-2 (SLC29A2) has been mapped to human chromosome 11q13. RT-PCR analysis showed expression of SLC29A2 in skeletal muscle, liver, lung, brain, kidney, heart, pancreas, and placenta. GFP (green flourescent protein) tagging showed presence of the protein on the basolateral membrane in renal epithelial cells. The di-leucine motif in SLC29A2 is important for the surface expression of the protein.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions

Solute carrier family 29 member-2 (SLC29A2) is a nucleoside transporter which mediates transport of pyrimidine nucleoside uridine and the purine nucleoside adenosine. It plays a key role in regulation of many physiological processes through its effect on adenosine concentration at the cell surface. Acute pulmonary inflammation causes transcriptional repression of SLC29A2, amplifying the extracellular accumulation of protective adenosine. Similarly, siRNA-mediated silencing of SLC29A2 increases mucosal adenosine signaling and attenuates hypoxia-associated inflammation of the intestine. The protein responds positively to fludarabine cytotoxicity in chronic lymphocytic leukemia cells, signifying its importance in chronic lymphocytic leukemia chemotherapy.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

This study examined the roles of human nucleoside transporters (hNTs) in mediating transepithelial fluxes of adenosine, 2'-deoxyadenosine, and three purine nucleoside anti-cancer drugs across polarized monolayers of human renal proximal tubule cells (hRPTCs), which were shown in previous studies to...

The surface of the intestinal mucosa is particularly prone to hypoxia-induced inflammation. Previous studies implicated signaling via extracellular adenosine in endogenous attenuation of intestinal inflammation; we investigated whether epithelial adenosine transport could reduce hypoxia-induced inflammation of the mucosa. We performed...
