Contributes to the renal and hepatic elimination of endogenous organic compounds from the systemic circulation into the urine and bile, respectively .
PMID:11327718 PMID:25904762
Capable of transporting a wide range of purine and pyrimidine nucleobases, nucleosides and nucleotides, with cGMP, 2'deoxyguanosine and GMP being the preferred substrates .
PMID:11327718 PMID:18216183 PMID:26377792 PMID:28945155
Functions as a pH- and chloride-independent cGMP bidirectional facilitative transporter that can regulate both intracellular and extracellular levels of cGMP and may be involved in cGMP signaling pathways .
PMID:18216183 PMID:26377792
Mediates orotate/glutamate bidirectional exchange and most likely display a physiological role in hepatic release of glutamate into the blood .
PMID:21446918
Involved in renal secretion and possible reabsorption of creatinine .
PMID:25904762 PMID:28945155
