May play a role in regulating central nervous system homeostasis of monoamine neurotransmitters. May be involved in luminal transport of organic cations in the kidney and seems to use luminal proton gradient to drive organic cation reabsorption. Does not seem to transport nucleoside and nucleoside analogs such as uridine, cytidine, thymidine, adenosine, inosine, guanosine, and azidothymidine. In (PubMed:16873718) adenosine is efficiently transported but in a fashion highly sensitive to extracellular pH, with maximal activity in the pH range 5.5 to 6.5. Glu-206 is essential for the cation selectivity and may function as the charge sensor for cationic substrates. Transport is chloride and sodium-independent but appears to be sensitive to changes in membrane potential. Weakly inhibited by the classical inhibitors of equilibrative nucleoside transport, dipyridamole, dilazep, and nitrobenzylthioinosine. May play a role in the regulation of extracellular adenosine concentrations in cardiac tissues, in particular during ischemia. {ECO:0000269|PubMed:15448143, ECO:0000269|PubMed:16873718, ECO:0000269|PubMed:17018840, ECO:0000269|PubMed:17121826}. |Nucleoside tran| |monoamine transmembrane transporter activity| |nucleoside transmembrane transporter activity| |nucleoside transmembrane transport| |nucleoside transport| |monoamine transport| |carbohydrate derivative transport| |nucleobase-containing compound transport| |apical plasma membrane| |transmembrane transport| |nitrogen compound transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp457|Bisphenol F 50μM R08 exp457]]|-1.83| |[[:results:exp453|B02 10μM R08 exp453]]|-1.75| |[[:results:exp64|Nocodazole 0.2μM R02 exp64]]|1.72| |[[:results:exp94|Nocodazole 0.1μM R03 exp94]]|1.81| |[[:results:exp93|DABN racemic mixture R03 exp93]]|2.13| |[[:results:exp256|HMS-I1 10μM R06 exp256]]|2.33| |[[:results:exp24|Nocodazole 0.2μM R00 exp24]]|2.48| |[[:results:exp244|SB743921 0.001μM R05 exp244]]|2.97| |[[:results:exp208|Vinblastine 0.015μM R05 exp208]]|3.34| No correlation found to any other genes in chemogenomics.
