Summaries for SLC6A4 Gene

Entrez Gene Summary for SLC6A4 Gene

  • This gene encodes an integral membrane protein that transports the neurotransmitter serotonin from synaptic spaces into presynaptic neurons. The encoded protein terminates the action of serotonin and recycles it in a sodium-dependent manner. This protein is a target of psychomotor stimulants, such as amphetamines and cocaine, and is a member of the sodium:neurotransmitter symporter family. A repeat length polymorphism in the promoter of this gene has been shown to affect the rate of serotonin uptake and may play a role in sudden infant death syndrome, aggressive behavior in Alzheimer disease patients, and depression-susceptibility in people experiencing emotional trauma.

GeneCards Summary for SLC6A4 Gene

SLC6A4 (Solute Carrier Family 6 (Neurotransmitter Transporter), Member 4) is a Protein Coding gene. Diseases associated with SLC6A4 include obsessive-compulsive disorder and slc6a4-related behavior disorders. Among its related pathways are SIDS Susceptibility Pathways and Circadian entrainment. GO annotations related to this gene include protein homodimerization activity and Rab GTPase binding. An important paralog of this gene is SLC6A13.

UniProtKB/Swiss-Prot for SLC6A4 Gene

  • Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.

Tocris Summary for SLC6A4 Gene

  • 5-HT transporters (serotonin transporters, SERT) are sodium- and chloride-dependent members of the solute carrier family 6 (SLC6) found widely distributed throughout the brain. They are responsible for re-uptake of 5-HT and undergo a conformational change to move one or more molecules per cycle. Structural motifs include 12-TM domains, extracellular loops, cytoplasmic C- and N-termini, putative phosphorylation sites acting as potential targets for PKA and PKC and regions essential for 5-HT selective affinity. There is evidence to suggest that SERTs are linked to neuroticism, sexual behavior, alcoholism, clinical depression, hypertension and obsessive-compulsive disorder.

Interacts with filamentous actin and STX1A (By similarity). Interacts (via C-terminus) with VIM. Interacts (via C-terminus) with SCAMP2; the interaction is direct and retains transporter molecules intracellularly.

Post-translational modifications for SLC6A4 Gene

  • Glycosylated; modification with sialylated N-glycans is a requirement for transporters to associate with each other and to function as homooligomeric forms.
  • Phosphorylation at Thr-276 increases 5-HT uptake and is required for cGMP-mediated SERT regulation. Phosphorylation upon PKC stimulation modifies the SERT distribution and density in the membrane, and diminishes the uptake capacity.
  • Glycosylation at Asn208 and Asn217
  • Modification sites at PhosphoSitePlus

Variants for SLC6A4 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for SLC6A4 Gene

A polymorphism in the promoter region (5-HTT gene-linked polymorphic region, 5-HTTLPR) is located approximately 1 kb upstream of the transcription initiation site and is composed of 16 repeat elements. The polymorphism consists of a 44-bp insertion or deletion involving repeat elements 6 to 8. The short allele is associated with lower transcriptional efficiency of the promoter compared with the long allele. Over half of the Caucasian population has a short allele. Individuals with one or two copies of the short allele exhibit more depressive symptoms, diagnosable depression and suicidality in relation to stressful life events than individuals homozygous for the long allele
