SLC6A11. also known as the GABA transporter 4 (GAT4), is a member of the solute carrier family 6 (SLC6) of neurotransmitter transporters. It plays a critical role in regulating synaptic neurotransmission by mediating the sodium- and chloride-dependent uptake of γ-aminobutyric acid (GABA), the primary inhibitory neurotransmitter in the central nervous system. SLC6A11 is predominantly expressed in the brain, particularly in astrocytes and certain neuronal populations, where it helps maintain GABA homeostasis by clearing excess neurotransmitter from synaptic clefts, thereby fine-tuning inhibitory signaling.
The recombinant human SLC6A11 protein is generated through heterologous expression systems (e.g., mammalian or insect cell lines) to study its structure, function, and interactions. It typically retains key features of the native protein, including 12 transmembrane domains and intracellular N- and C-terminal regulatory regions. Recombinant versions enable investigations into transport kinetics, pharmacology, and mutations linked to neurological disorders. Research on SLC6A11 has implications for understanding epilepsy, anxiety, and depression, as dysregulation of GABAergic signaling is implicated in these conditions. Additionally, it serves as a potential target for developing drugs that modulate GABA uptake, such as antiepileptics or antidepressants. Structural studies using recombinant proteins also aid in elucidating mechanisms of transporter inhibition or allosteric regulation.
