The human dopamine transporter (DAT), encoded by the SLC6A3 gene, is a presynaptic membrane protein responsible for reuptaking synaptic dopamine into neurons, thereby regulating dopaminergic neurotransmission. As a member of the solute carrier 6 (SLC6) family, it utilizes sodium and chloride gradients to transport dopamine across cell membranes. Dysregulation of DAT function is linked to neurological and psychiatric disorders, including Parkinson's disease, attention-deficit/hyperactivity disorder (ADHD), and drug addiction.
Recombinant human DAT refers to the protein produced through genetic engineering, typically expressed in heterologous systems like mammalian cells (e.g., HEK293), insect cells, or bacterial models. Its recombinant form enables detailed structural and functional studies, overcoming challenges in isolating native DAT from brain tissue. Researchers use it to investigate transport mechanisms, ligand interactions (e.g., cocaine, amphetamines), and pharmacotherapeutic targets.
Structural studies of recombinant DAT, often stabilized in specific conformations, have revealed insights into substrate recognition, inhibitor binding pockets, and conformational dynamics during transport cycles. This knowledge aids in developing DAT-targeted drugs for neuropsychiatric conditions or molecular imaging probes (e.g., for PET scans). However, maintaining functional activity during recombinant production requires careful optimization of expression conditions and post-translational modifications. Current research also explores DAT's role in cellular signaling beyond neurotransmitter recycling, highlighting its broader physiological implications.
