The purpose of this study is to determine the localization of nucleoside transporters expressed within rat epididymis to demonstrate the potential of epididymal reabsorption. Using immunohistochemistry, we determined that equilibrative nucleoside transporter 1 (ENT1) is localized to the basolateral membrane of epithelial cells, ENT2 is expressed in the nucleus of the epithelium and CNT2 is expressed by basal cells.

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.
