EAAT5 (Excitatory Amino Acid Transporter 5), also known as SLC1A7. is a member of the solute carrier 1 (SLC1) family of neurotransmitter transporters. It primarily functions as a sodium- and potassium-dependent glutamate transporter, playing a critical role in regulating extracellular glutamate concentrations in the central nervous system (CNS) and retina. Unlike other EAAT subtypes (EAAT1-4), EAAT5 is predominantly expressed in retinal photoreceptors and bipolar cells, where it modulates synaptic transmission by rapidly clearing glutamate released during visual signaling. This helps maintain neuronal excitability and prevents glutamate-induced excitotoxicity, a mechanism implicated in neurodegenerative disorders.
Recombinant EAAT5 protein is produced using genetic engineering techniques, typically by expressing the human SLC1A7 gene in heterologous systems like mammalian cells (e.g., HEK293) or insect cells. These systems enable proper post-translational modifications, ensuring functional and structural fidelity to the native protein. The purified recombinant protein retains glutamate transport activity and ion dependency, making it a valuable tool for in vitro studies. Researchers use it to investigate transport kinetics, ligand interactions, and the impact of mutations linked to retinal or neurological diseases. Additionally, it aids in drug discovery for conditions like glaucoma, epilepsy, or ischemic brain injury, where glutamate dysregulation is a key pathological feature. Its unique localization and functional properties distinguish EAAT5 as a target for understanding visual neurotransmission and developing tissue-specific therapeutic strategies.
