Summary
Enables purine nucleoside transmembrane transporter activity. Predicted to be involved in several processes, including nucleoside transport; protein localization to cell surface; and purine nucleobase transmembrane transport. Located in brush border membrane. Is expressed in foregut-midgut junction; midgut; and placenta. Orthologous to human SLC28A2 (solute carrier family 28 member 2). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Biased expression in small intestine adult (RPKM 25.8), large intestine adult (RPKM 20.5) and 7 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
