Many physiological, endocrine and behavioral functions are determined and regulated by monoamine signaling1,2. Many brain disorders such as depression, drug abuse, schizophrenia, attention deficit hyperactivity disorder (ADHD) are caused by the malfunction of monoaminergic transmission1-3. The intensity of monoaminergic signaling is determined by the availability of the monoamine, which is in turn determined in part by its uptake from the extracellular milieu via monoamine transporters. These transporters include DAT, SERT, and NET, responsible for uptaking dopamine, serotonin (5-HT) and noradrenaline respectively, and recycling them back for release3-5.
DAT, SERT and NET are members of the Na+/Cl- dependent membrane transporter family which also includes other members. These transporters consist of 12 transmembrane domains and intracellular N- and C-termini. Like its counterparts, SERT’s intracellular N- and C-terminal domains are also subject to phosphorylation and protein-protein interactions important for modulating its activity and localization6.
SERTs are evidently expressed in serotonergic neurons, and are also expressed in various peripheral tissues including specialized cells of the gut, placenta, lung, blood lymphocytes and platelets6.
SERT knockout mice are viable and as a consequence exhibit increased extracellular levels of 5-HT and significantly decreased levels of brain tissue 5-HT due to deficient recycling and re-accumulation of serotonin by SERT7,8. Phenotypes displayed by SERT knockout mice include stress sensitivity, obesity and various behavioral changes9.
Anti-Serotonin Transporter (SERT) (extracellular) Antibody (#AMT-004) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunohistochemistry, immunocytochemistry, indirect flow cytometry, and live cell imaging applications. It has been designed to recognize SERT from human, mouse, and rat samples.
Anti-Serotonin Transporter (SERT) (extracellular)-FITC Antibody (#AMT-004-F) is directly conjugated to fluorescein isothiocyanate (FITC). The antibody can be used in immunofluorescent applications such as direct live cell flow cytometry.
