The SLC1A6 gene encodes the excitatory amino acid transporter 4 (EAAT4), a member of the solute carrier family 1. EAAT4 is a high-affinity glutamate transporter responsible for clearing glutamate from the extracellular space in specific brain regions, particularly the cerebellum and cerebral cortex.
EAAT4 operates as a sodium-dependent glutamate transporter, cotransporting one glutamate molecule with three sodium ions and one hydrogen ion, while countertransporting one potassium ion. This electrogenic process maintains low extracellular glutamate concentrations, preventing excitotoxicity which can lead to neuronal damage.
EAAT4 has a distinctive structure with eight transmembrane domains and a intracellular C-terminus. The protein is unique among EAATs in its high expression in Purkinje cells of the cerebellum, where it plays a critical role in modulating cerebellar synaptic plasticity and motor learning. Dysfunction of EAAT4 has been implicated in epilepsy, ataxia, and various neurodegenerative conditions where excitotoxicity plays a role.

SLC1A6/EAAT4 is predominantly expressed in:
The highest expression is in cerebellar Purkinje cells, where EAAT4 is localized to the dendritic spines and extrasynaptic membranes, serving as a major glutamate clearance mechanism.
