The dopamine transporter (DAT, also sodium-dependent dopamine transporter) is a membrane-spanning protein coded for in humans by the SLC6A3 gene (also known as DAT1), that pumps the neurotransmitter dopamine out of the synaptic cleft back into cytosol. In the cytosol, other transporters sequester the dopamine into vesicles for storage and later release. Dopamine reuptake via DAT provides the primary mechanism through which dopamine is cleared from synapses, although there may be an exception in the prefrontal cortex, where evidence points to a possibly larger role of the norepinephrine transporter.[5]

DAT is implicated in a number of dopamine-related disorders, including attention deficit hyperactivity disorder, bipolar disorder, clinical depression, eating disorders, and substance use disorders. The gene that encodes the DAT protein is located on chromosome 5, consists of 15 coding exons, and is roughly 64 kbp long. Evidence for the associations between DAT and dopamine related disorders has come from a type of genetic polymorphism, known as a variable number tandem repeat, in the SLC6A3 gene, which influences the amount of protein expressed.[6]

Function

[edit]

DAT is an integral membrane protein that removes dopamine from the synaptic cleft and deposits it into surrounding cells, thus terminating the signal of the neurotransmitter. Dopamine underlies several aspects of cognition, including reward, and DAT facilitates regulation of that signal.[7]

Mechanism

[edit]

DAT is a symporter that moves dopamine across the cell membrane by coupling the movement to the energetically-favorable movement of sodium ions moving from high to low concentration into the cell. DAT function requires the sequential binding and co-transport of two Na+ ions and one Cl− ion with the dopamine substrate. The driving force for DAT-mediated dopamine reuptake is the ion concentration gradient generated by the plasma membrane Na+/K+ ATPase.[8]

In the most widely accepted model for monoamine transporter function, sodium ions must bind to the extracellular domain of the transporter before dopamine can bind. Once dopamine binds, the protein undergoes a conformational change, which allows both sodium and dopamine to unbind on the intracellular side of the membrane.[9]

Studies using electrophysiology and radioactive-labeled dopamine have confirmed that the dopamine transporter is similar to other monoamine transporters in that one molecule of neurotransmitter can be transported across the membrane with one or two sodium ions. Chloride ions are also needed to prevent a buildup of positive charge. These studies have also shown that transport rate and direction is totally dependent on the sodium gradient.[10]

Because of the tight coupling of the membrane potential and the sodium gradient, activity-induced changes in membrane polarity can dramatically influence transport rates. In addition, the transporter may contribute to dopamine release when the neuron depolarizes.[10]

DAT–Cav coupling

[edit]

Preliminary evidence suggests that the dopamine transporter couples to L-type voltage-gated calcium channels (particularly Cav1.2 and Cav1.3), which are expressed in virtually all dopamine neurons.[11] As a result of DAT–Cav coupling, DAT substrates that produce depolarizing currents through the transporter are able to open calcium channels that are coupled to the transporter, resulting in a calcium influx in dopamine neurons.[11] This calcium influx is believed to induce CAMKII-mediated phosphorylation of the dopamine transporter as a downstream effect;[11] since DAT phosphorylation by CAMKII results in dopamine efflux in vivo, activation of transporter-coupled calcium channels is a potential mechanism by which certain drugs (e.g., amphetamine) trigger neurotransmitter release.[11]

Protein structure

[edit]

The initial determination of the membrane topology of DAT was based upon hydrophobic sequence analysis and sequence similarities with the GABA transporter. These methods predicted twelve transmembrane domains (TMD) with a large extracellular loop between the third and fourth TMDs.[12] Further characterization of this protein used proteases, which digest proteins into smaller fragments, and glycosylation, which occurs only on extracellular loops, and largely verified the initial predictions of membrane topology.[13] The exact structure of the Drosophila melanogaster dopamine transporter (dDAT) was elucidated in 2013 by X-ray crystallography.[14]

Amphetamine enters the presynaptic neuron across the neuronal membrane or through DAT.[15] Once inside, it binds to TAAR1 or enters synaptic vesicles through VMAT2.[15][16] When amphetamine enters synaptic vesicles through VMAT2, it collapses the vesicular pH gradient, which in turn causes dopamine to be released into the cytosol (light tan-colored area) through VMAT2.[16][17] When amphetamine binds to TAAR1, it reduces the firing rate of the dopamine neuron via G protein-coupled inwardly rectifying potassium channels (GIRKs) and activates protein kinase A (PKA) and protein kinase C (PKC), which subsequently phosphorylate DAT.[15][18][19] PKA phosphorylation causes DAT to withdraw into the presynaptic neuron (internalize) and cease transport.[15] PKC-phosphorylated DAT may either operate in reverse or, like PKA-phosphorylated DAT, internalize and cease transport.[15] Amphetamine is also known to increase intracellular calcium, an effect which is associated with DAT phosphorylation through a CAMKIIα-dependent pathway, in turn producing dopamine efflux.[20][21]


Regional distribution of DAT has been found in areas of the brain with established dopaminergic circuitry, including the nigrostriatal, mesolimbic, and mesocortical pathways.[22] The nuclei that make up these pathways have distinct patterns of expression. Gene expression patterns in the adult mouse show high expression in the substantia nigra pars compacta.[23]

DAT in the mesocortical pathway, labeled with radioactive antibodies, was found to be enriched in dendrites and cell bodies of neurons in the substantia nigra pars compacta and ventral tegmental area. This pattern makes sense for a protein that regulates dopamine levels in the synapse.

Staining in the striatum and nucleus accumbens of the mesolimbic pathway was dense and heterogeneous. In the striatum, DAT is localized in the plasma membrane of axon terminals. Double immunocytochemistry demonstrated DAT colocalization with two other markers of nigrostriatal terminals, tyrosine hydroxylase and D2 dopamine receptors. The latter was thus demonstrated to be an autoreceptor on cells that release dopamine. TAAR1 is a presynaptic intracellular receptor that is also colocalized with DAT and which has the opposite effect of the D2 autoreceptor when activated;[15][24] i.e., it internalizes dopamine transporters and induces efflux through reversed transporter function via PKA and PKC signaling.

Surprisingly, DAT was not identified within any synaptic active zones. These results suggest that striatal dopamine reuptake may occur outside of synaptic specializations once dopamine diffuses from the synaptic cleft.

In the substantia nigra, DAT is localized to axonal and dendritic (i.e., pre- and post-synaptic) plasma membranes.[25]

Within the perikarya of pars compacta neurons, DAT was localized primarily to rough and smooth endoplasmic reticulum, Golgi complex, and multivesicular bodies, identifying probable sites of synthesis, modification, transport, and degradation.[26]

Genetics and regulation

[edit]

The gene for DAT, known as DAT1, is located on chromosome 5p15.[6] The protein encoding region of the gene is over 64 kb long and comprises 15 coding segments or exons.[27] This gene has a variable number tandem repeat (VNTR) at the 3’ end (rs28363170) and another in the intron 8 region.[28] Differences in the VNTR have been shown to affect the basal level of expression of the transporter; consequently, researchers have looked for associations with dopamine-related disorders.[29]

Nurr1, a nuclear receptor that regulates many dopamine-related genes, can bind the promoter region of this gene and induce expression.[30] This promoter may also be the target of the transcription factor Sp-1.

While transcription factors control which cells express DAT, functional regulation of this protein is largely accomplished by kinases. MAPK,[31] CAMKII,[20][21] PKA,[15] and PKC[21][32] can modulate the rate at which the transporter moves dopamine or cause the internalization of DAT. Co-localized TAAR1 is an important regulator of the dopamine transporter that, when activated, phosphorylates DAT through protein kinase A (PKA) and protein kinase C (PKC) signaling.[15][33] Phosphorylation by either protein kinase can result in DAT internalization (non-competitive reuptake inhibition), but PKC-mediated phosphorylation alone induces reverse transporter function (dopamine efflux).[15][34] Dopamine autoreceptors also regulate DAT by directly opposing the effect of TAAR1 activation.[15]

The human dopamine transporter (hDAT) contains a high affinity extracellular zinc binding site which, upon zinc binding, inhibits dopamine reuptake and amplifies amphetamine-induced dopamine efflux in vitro.[35][36][37] In contrast, the human serotonin transporter (hSERT) and human norepinephrine transporter (hNET) do not contain zinc binding sites.[37] Zinc supplementation may reduce the minimum effective dose of amphetamine when it is used for the treatment of attention deficit hyperactivity disorder.[38]

Biological role and disorders

[edit]

The rate at which DAT removes dopamine from the synapse can have a profound effect on the amount of dopamine in the cell. This is best evidenced by the severe cognitive deficits, motor abnormalities, and hyperactivity of mice with no dopamine transporters.[39] These characteristics have striking similarities to the symptoms of ADHD.

Differences in the functional VNTR have been identified as risk factors for bipolar disorder[40] and ADHD.[41][42] Data has emerged that suggests there is also an association with stronger withdrawal symptoms from alcoholism, although this is a point of controversy.[43][44] An allele of the DAT gene with normal protein levels is associated with non-smoking behavior and ease of quitting.[45] Additionally, male adolescents particularly those in high-risk families (ones marked by a disengaged mother and absence of maternal affection) who carry the 10-allele VNTR repeat show a statistically significant affinity for antisocial peers.[46][47]

Increased activity of DAT is associated with several different disorders, including clinical depression.[48]

Mutations in DAT have been shown to cause dopamine transporter deficiency syndrome, an autosomal recessive movement disorder characterized by progressively worsening dystonia and parkinsonism.[49]

Pharmacology

[edit]

The dopamine transporter is the target of substrates, dopamine releasers, transport inhibitors and allosteric modulators.[50][51]

Cocaine blocks DAT by binding directly to the transporter and reducing the rate of transport.[12] In contrast, amphetamine enters the presynaptic neuron directly through the neuronal membrane or through DAT, competing for reuptake with dopamine. Once inside, it binds to TAAR1 or enters synaptic vesicles through VMAT2. When amphetamine binds to TAAR1, it reduces the firing rate of the postsynaptic neuron and triggers protein kinase A and protein kinase C signaling, resulting in DAT phosphorylation. Phosphorylated DAT then either operates in reverse or withdraws into the presynaptic neuron and ceases transport. When amphetamine enters the synaptic vesicles through VMAT2, dopamine is released into the cytosol.[15][16] Amphetamine also produces dopamine efflux through a second TAAR1-independent mechanism involving CAMKIIα-mediated phosphorylation of the transporter, which putatively arises from the activation of DAT-coupled L-type calcium channels by amphetamine.[11]

The dopaminergic mechanisms of each drug are believed to underlie the pleasurable feelings elicited by these substances.[7]

Interactions

[edit]

Dopamine transporter has been shown to interact with:

Apart from these innate protein-protein interactions, recent studies demonstrated that viral proteins such as HIV-1 Tat protein interacts with the DAT[57][58] and this binding may alter the dopamine homeostasis in HIV positive individuals which is a contributing factor for the HIV-associated neurocognitive disorders.[59]

One example of interest is CaMKII, which has been well characterized as an effector of Ca2+ currents downstream of L-type Ca2+ channels [21,22]. Interestingly, DAT is a CaMKII substrate and phosphorylated DAT favors the reverse transport of dopamine [48,49], constituting a possible mechanism by which electrical activity and L-type Ca2+ channels may modulate DAT states and dopamine release. ... In summary, our results suggest that pharmacologically, S(+)AMPH is more potent than DA at activating hDAT-mediated depolarizing currents, leading to L-type Ca2+ channel activation, and the S(+)AMPH-induced current is more tightly coupled than DA to open L-type Ca2+ channels.

Amphetamine and its derivatives like methamphetamine are weak base compounds that are the only widely used class of drugs known to elicit transmitter release by a non-exocytic mechanism. As substrates for both DAT and VMAT, amphetamines can be taken up to the cytosol and then sequestered in vesicles, where they act to collapse the vesicular pH gradient.

ISSN 0009-3122. Phenylpiracetam was originally designed as a nootropic drug for the sustenance and improvement of the physical condition and cognition abilities of Soviet space crews.2 Later, especially during the last decade, phenylpiracetam was introduced into general clinical practice in Russia and in some Eastern European countries. The possible target receptors and mechanisms for the acute activity of this drug remained unclear, until very recently it was found that (R)-phenylpiracetam (5) (MRZ-9547) is a selective dopamine transporter inhibitor that moderately stimulates striatal dopamine release.19

Here, we tested the effects of MRZ-9547 [...], and its l-enantiomer MRZ-9546 on effort-related decision making in rats. The racemic form of these compounds referred to as phenotropil has been shown to stimulate motor activity in rats (Zvejniece et al., 2011) and enhance physical capacity and cognition in humans (Malykh and Sadaie, 2010). [...] MRZ-9547 turned out to be a DAT inhibitor as shown by displacement of binding of [125I] RTI-55 (IC50 = 4.82 ± 0.05 μM, n=3) to human recombinant DAT expressed in CHO-K1 cells and inhibition of DA uptake (IC50 = 14.5 ± 1.6 μM, n=2) in functional assays in the same cells. It inhibited norepinephrine transporter (NET) with an IC50 of 182 μM (one experiment in duplicate). The potencies for the l-enantiomer MRZ-9546 were as follows: DAT binding (Ki = 34.8 ± 14.8 μM, n=3), DAT function (IC50 = 65.5 ± 8.3 μM, n=2) and NET function (IC50 = 667 μM, one experiment performed in duplicate).

PMID 30513290. In a study performed by Sommer et al. (2014), healthy rats treated with the selective dopamine transport (DAT) inhibitor MRZ-9547 (Fig. 1) chose high effort, high reward more often than their untreated matched controls. Unlike similar studies, however, depressive symptoms were not induced before treatment; rather, baseline healthy controls were compared to healthy rats treated with MRZ-9547. [...] In one study, the selective DAT inhibitor MRZ-9547 increased the number of lever presses more than untreated controls (Sommer et al., 2014). The investigators concluded that such effort-based "decision making in rodents could provide an animal model for motivational dysfunctions related to effort expenditure such as fatigue, e.g. in Parkinson's disease or major depression." Based upon the findings with MRZ-9547, they suggested that this drug mechanism might be a valuable therapeutic entity for fatigue in neurological and neuropsychiatric disorders. [...] A high effort bias been reported with bupropion (Randall et al., 2015), lisdexamfetamine (Yohn etal., 2016e), and the DA uptake blockers MRZ-9547 (Sommer et al., 2014), PRX-14040 (Fig. 1) (Yohn et al., 2016d) and GBR12909 (Fig. 1) (Yohn et al., 2016c).
