Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

commentFUNCTION Sodium-dependent and purine-selective transporter (PubMed:10087507, PubMed:9435697). Exhibits the transport characteristics of the nucleoside transport system cif or N1 subtype (N1/cif) (selective for purine nucleosides and uridine) (PubMed:10087507, PubMed:21795683, PubMed:9435697). Plays a critical role in specific uptake and salvage of purine nucleosides in kidney and other tissues (PubMed:9435697). May contribute to regulate the transport of organic compounds in testes across the blood-testis-barrier (Probable).CATALYTIC ACTIVITY adenosine(out) + Na(+)(out) = adenosine(in) + Na(+)(in)CATALYTIC ACTIVITY inosine(out) + Na(+)(out) = inosine(in) + Na(+)(in)CATALYTIC ACTIVITY guanosine(out) + Na(+)(out) = guanosine(in) + Na(+)(in)CATALYTIC ACTIVITY uridine(out) + Na(+)(out) = uridine(in) + Na(+)(in)ACTIVITY REGULATION Inhibited by formycin B.SUBCELLULAR LOCATION Localized to the apicolateral membranes of Sertoli cells and vascular endothelial cells in testis.TISSUE SPECIFICITY Expressed in heart and skeletal muscle followed by liver, kidney, intestine, pancreas, placenta and brain (PubMed:9435697). Weak expression in lung (PubMed:9435697). In testis, primarily localized to the apicolateral membranes of Sertoli cells and vascular endothelial cells, and weakly expressed in Leydig cells, peritubular myoid cells and germ cells (PubMed:35307651).SIMILARITY Belongs to the concentrative nucleoside transporter (CNT) (TC 2.A.41) family.
