Summary: Enables several functions, including monoamine transmembrane transporter activity; organic cation transmembrane transporter activity; and toxin transmembrane transporter activity. Involved in several processes, including acetylcholine transport; histamine transport; and monoamine transport. Located in apical plasma membrane and basolateral plasma membrane. Is active in cholinergic synapse; presynaptic membrane; and synaptic vesicle membrane. Used to study acute kidney failure. Biomarker of cholestasis (multiple); hyperuricemia; and kidney failure (multiple). Human ortholog(s) of this gene implicated in acute kidney failure. Orthologous to human SLC22A2 (solute carrier family 22 member 2). [provided by Alliance of Genome Resources, Jan 2025]

Neuronal uptake transporters contribute to oxaliplatin neurotoxicity in mice.
Title: Neuronal uptake transporters contribute to oxaliplatin neurotoxicity in mice.
Although multiple factors may influence renal handling of drugs, these observations can be accounted for, at least in part, by downregulation of Mate1-mediated apical efflux from tubular cells and Oct2-mediated basolateral uptake. Our results suggest that hyperuricemia could alter the disposition of drugs that are substrates of Mate1 and/or Oct2.
Title: Changes of drug pharmacokinetics mediated by downregulation of kidney organic cation transporters Mate1 and Oct2 in a rat model of hyperuricemia.
findings indicate that OCT2 knockout possibly mitigate OTA-induced apoptosis by preventing the increase of Caspase 3 and CDK1
Title: Mitigation of cell apoptosis induced by ochratoxin A (OTA) is possibly through organic cation transport 2 (OCT2) knockout.
These results provide the first identification of a high affinity neuronal transporter for p-tyramine, and also confirm the recently described localization of OCT2 in pre-synaptic terminals.

Data show that lycopene upregulated the organic anion transporters (OAT1 and OAT3) and organic cation transporters (OCT1 and OCT2) in cisplatin-induced acute renal injury.
Title: Effect of lycopene against cisplatin-induced acute renal injury in rats: organic anion and cation transporters evaluation.
liver I/R decreases the tubular secretion of cimetidine, mainly because of the decreased rOCT2 level in the kidney, and that oxidative stress should be responsible in part for decreased renal rOCT2 after liver I/R injury.
Title: Altered pharmacokinetics of cimetidine caused by down-regulation of renal rat organic cation transporter 2 (rOCT2) after liver ischemia-reperfusion injury.

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.
