**Background of Recombinant Human SLC18A1 Protein**
The SLC18A1 gene encodes vesicular monoamine transporter 1 (VMAT1), a member of the solute carrier 18 (SLC18) family. This transmembrane protein localizes to synaptic, endocrine, and neuroendocrine vesicles, where it transports monoamine neurotransmitters (e.g., serotonin, dopamine, norepinephrine) into vesicles via a proton gradient-dependent mechanism. By packaging monoamines into secretory vesicles, VMAT1 ensures their regulated release, critical for neurotransmission and hormonal signaling.
SLC18A1 is expressed in peripheral tissues (e.g., adrenal glands, stomach) and the central nervous system, with polymorphisms linked to neuropsychiatric disorders like schizophrenia, bipolar disorder, and Parkinson’s disease. Research highlights its role in monoaminergic dysfunction and response to psychoactive drugs.
Recombinant human SLC18A1 protein, produced in heterologous expression systems (e.g., mammalian cells), retains native structural and functional properties. It is widely utilized to study transporter kinetics, ligand interactions, and pathological mutations. Its applications span drug discovery (e.g., antipsychotics, antidepressants) and mechanistic investigations into monoamine homeostasis, offering insights for therapeutic targeting in neurological and metabolic diseases.
