**Background of SERT Recombinant Protein**
The serotonin transporter (SERT), encoded by the *SLC6A4* gene, is a transmembrane protein responsible for the reuptake of serotonin (5-HT) from synaptic clefts into presynaptic neurons, thereby regulating serotonergic signaling. As a member of the solute carrier 6 (SLC6) family, SERT plays a critical role in neurotransmission, mood regulation, and cognitive processes. Dysregulation of SERT function is linked to psychiatric disorders, including depression, anxiety, and obsessive-compulsive disorder, making it a key target for antidepressants like selective serotonin reuptake inhibitors (SSRIs).
Recombinant SERT proteins are engineered in vitro using heterologous expression systems (e.g., bacterial, insect, or mammalian cells) to study its structure, function, and interactions. These systems enable large-scale production of purified, bioactive SERT, overcoming challenges in isolating the native protein from neural tissues. Structural studies using recombinant SERT have revealed its 12-transmembrane domain architecture, ligand-binding sites, and mechanisms of ion-coupled transport. For instance, cryo-EM and X-ray crystallography analyses have provided insights into how SSRIs and other inhibitors bind to SERT, guiding drug development.
Additionally, recombinant SERT is pivotal in high-throughput drug screening, toxicity testing, and investigating genetic variants (e.g., SERT polymorphisms linked to altered drug responses). Mutagenesis studies using recombinant proteins help clarify the impact of specific residues on transporter activity, substrate specificity, and disease-associated mutations.
Overall, SERT recombinant proteins serve as indispensable tools for advancing neuropharmacology, molecular psychiatry, and therapeutic innovation.
