**Background of Slc17a8 Recombinant Protein**
Slc17a8. a member of the solute carrier 17 (SLC17) transporter family, encodes vesicular glutamate transporter 3 (VGLUT3), which packages the excitatory neurotransmitter glutamate into synaptic vesicles for regulated release. This transporter is critical for glutamatergic signaling in specific neuronal and non-neuronal circuits. Unlike other VGLUT isoforms (VGLUT1/2), VGLUT3 is expressed in distinct populations of cells, including auditory inner hair cells, retinal amacrine cells, and subsets of serotoninergic or cholinergic neurons, enabling glutamate co-transmission in these systems.
Recombinant Slc17a8 protein is produced by cloning the Slc17a8 gene into expression vectors, followed by transfection into host systems (e.g., mammalian cells, bacteria, or yeast) to enable large-scale protein synthesis. The purified protein retains its functional domains, including 12 transmembrane helices responsible for proton-coupled glutamate transport. Researchers utilize this recombinant protein to study its kinetic properties, substrate specificity, and regulatory mechanisms, often through *in vitro* vesicle uptake assays or structural analyses like cryo-EM.
Studies on Slc17a8/VGLUT3 have revealed its role in hearing, vision, and neuropsychiatric disorders. Mutations in Slc17a8 are linked to auditory neuropathy, while its dysregulation is implicated in epilepsy, schizophrenia, and mood disorders. Recombinant Slc17a8 also aids in drug discovery, serving as a target for small molecules aiming to modulate glutamate signaling. Its unique expression pattern and functional versatility make it a key focus in neuroscience and therapeutic research.
