OCT3 is widely distributed in brain tissue. It is not yet completely clear whether its location is primarily neuronal or glial.

==Pharmacology== | |||
Organic cation transporter 3 is a polyspecific transporter whose transport is independent of sodium. Known substrates for transport include: [[histamine]], [[serotonin]], [[norepinephrine]], [[dopamine]] and [[MPP+]]. Capacity for transport and affinity for these substrates may vary between rat and human isoforms however.<ref name="pmid16581093"/> | |||
Transport activity of OCT3 is inhibited by recreational and pharmaceutical drugs, including [[MDMA]], [[phencyclidine]] (PCP), [[MK-801]], [[amphetamine]], [[methamphetamine]] and [[cocaine]].<ref name="pmid16581093"/> Transport is also inhibited by the chemical [[decynium-22]] and physiological concentrations of [[corticosterone]] and [[cortisol]]. K<sub>i</sub> values for decynium-22 and corticosterone inhibition of OCT3 transport are respectively 10 and 100 times lower than K<sub>i</sub> values of OCT1 and OCT2.<ref name="pmid12110607">{{cite journal | vauthors = Hayer-Zillgen M, Brüss M, Bönisch H | title = Expression and pharmacological profile of the human organic cation transporters hOCT1, hOCT2 and hOCT3 | journal = Br J Pharmacol| volume = 136| issue = 6| pages = 829–836 |date=Jul 2002| pmid = 12110607 | pmc = 1573414| doi =10.1038/sj.bjp.0704785 }}</ref> | |||

Solute carrier family 22 member 3 (SLC22A3) also known as the organic cation transporter 3 (OCT3) or extraneuronal monoamine transporter (EMT) is a protein that in humans is encoded by the SLC22A3 gene.[1][2][3]
Polyspecific organic cation transporters in the liver, kidney, intestine, and other organs are critical for elimination of many endogenous small organic cations as well as a wide array of drugs and environmental toxins. This gene is one of three similar cation transporter genes located in a cluster on chromosome 6. The encoded protein contains twelve putative transmembrane domains and is a plasma integral membrane protein.[3]
Distribution
OCT3 is widely distributed in brain tissue. It is not yet completely clear whether its location is primarily neuronal or glial. Areas of the brain in which it has been reported include: hippocampus, retrosplenial cortex, visual cortex, hypothalamus, amygdala, nucleus accumbens, thalamus, raphe nucleus, subiculum, superior and inferior colliculi, and islands of Calleja.[4][5]
Pharmacology
Organic cation transporter 3 is a polyspecific transporter whose transport is independent of sodium. Known substrates for transport include: histamine, serotonin, norepinephrine, dopamine and MPP+. Capacity for transport and affinity for these substrates may vary between rat and human isoforms however.[5]
Transport activity of OCT3 is inhibited by recreational and pharmaceutical drugs, including MDMA, phencyclidine (PCP), MK-801, amphetamine, methamphetamine and cocaine.[5] Transport is also inhibited by the chemical decynium-22 and physiological concentrations of corticosterone and cortisol. Ki values for decynium-22 and corticosterone inhibition of OCT3 transport are respectively 10 and 100 times lower than Ki values of OCT1 and OCT2.[6]
