SLC6A3 Membrane Protein Introduction

Introduction of SLC6A3

SLC6A3 is encoded by SLC6A3 gene. It belongs to the solute carrier family 6 which has been extensively studied during the past few decades because it offers numerous possibilities for therapeutic applications. It is a norepinephrine transporter which can remove norepinephrine from synaptic cleft to cytosol, and is responsible for the regulation of the rewarding and motivational processes underlying food intake and eating behaviors. Meanwhile, many studies conducted on SLC6A3 show that it is related with various diseases, such as idiopathic epilepsy, attention-deficit hyperactivity disorder and tobacco addiction.

Function of SLC6A3 Membrane Protein

SLC6A3, also named as dopamine transporter (DAT), is mainly expressed in the striatum. The SLC6A3 gene codes for a presynaptic transporter for uptake of dopamine, and thus affecting the amount of available dopamine in the synaptic cleft. Recent studies indicate that SLC6A3 variants are strongly associated with obesity features, metabolic profiles, and dietary intake. In addition, researches have confirmed several SLC6A3 SNPs could be potential therapeutic targets with the value in the early diagnosis and management of neurodevelopmental diseases in newborns.

Application of SLC6A3 Membrane Protein in Literature

  1. González-Giraldo Y., et al. Two dopaminergic genes, DRD4 and SLC6A3, are associated with body mass index in a Colombian sample of young adults. Arch Physiol Biochem. 2017, 16:1-5. PubMed ID: 29145734

    This article reports the association between the SLC6A3, DRD4 polymorphisms and body mass index in 232 Colombian young subjects. These results indicate that a significant association is found in these two genes and BMI in healthy young adults.

  2. Ludmer J.A., et al. Maternal DRD2, SLC6A3, and OXTR genotypes as potential moderators of the relation between maternal history of care and maternal cortisol secretion in the context of mother-infant separation. Biol Psychol. 2017, 129:154-164. PubMed ID: 28890000

    This article analyzes the relationship between DRD2, SLC6A3, and OXTR and cortisol secretion in anticipation of infant stress. These results indicate that DRD2, SLC6A3, and OXTR genetic characteristics are related to the maternal protective system and anticipatory cortisol secretion.

    Authors in this group analyze the expression and methylation levels of SLC6A3 in white blood cells of full-term newborns. The data show that highly methylation of SLC6A3 gene is one of risk factors for attention-deficit/hyperactivity disorder.

    This article conducts a meta-analyse to identify the association between SLC6A3 gene polymorphisms and methylphenidate in children with attention-deficit hyperactivity disorder (ADHD). The results suggest that SLC6A3 variants are strongly associated with severity of ADHD.

  5. Kurian M.A., et al. SLC6A3-related dopamine transporter deficiency syndrome. Gene Reviews. 2017. PubMed ID: 28749637

    This article conducts a case-control study to detect the expression of SLC6A3 and the gene polymorphisms in patients who suffer from dopamine transporter deficiency syndrome. The data illustrate that SLC6A3 variants are associated with the risk of DTDS.
