<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

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.4 Publications

Miscellaneous

This protein is the target of psychomotor stimulants such as amphetamines or cocaine.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i0EB535B0A579BDA2

<p>This subsection of the 'Sequence' section provides information on polymorphic variants. If the variant is associated with a disease state, the description of the latter can be found in the <a href="http://www.uniprot.org/manual/involvement%5Fin%5Fdisease">'Involvement in disease'</a> subsection.<p><a href='/help/polymorphism' target='_top'>More...</a></p>Polymorphismi

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.1 Publication
The 5-HTTLPR polymorphism may influence susceptibility to anxiety [MIMi:607834].1 Publication
The polymorphism Val-425 seems to be linked to a susceptibility to obsessive-compulsive disorder (OCD) [MIMi:164230].3 Publications
Genetic variations in SLC6A4 determine the genetic susceptibility to alcoholism [MIMi:103780].1 Publication
