Summary: Enables L-glutamate transmembrane transporter activity. Acts upstream of or within L-glutamate transmembrane transport; establishment of localization in cell; and regulation of membrane potential. Located in Golgi apparatus and membrane. Is active in glutamatergic synapse and presynaptic membrane. Is expressed in central nervous system and retina. Orthologous to human SLC1A6 (solute carrier family 1 member 6).

Title: MicroRNA-128 Protects Dopamine Neurons from Apoptosis and Upregulates the Expression of Excitatory Amino Acid Transporter 4 in Parkinson's Disease by Binding to AXIN1.
Loss of EAAT4 accounts for the initial hyper-excitability of Purkinje cells lacking b-III spectrin and that loss of GLAST appears to work synergistically to worsen motor deficits. When levels of both EAAT4 and GLAST are compromised in b-III(-/-) mice, the proximal dendrites of Purkinje cells within the posterior cerebellum are the most vulnerable to degeneration.
Title: Posterior cerebellar Purkinje cells in an SCA5/SPARCA1 mouse model are especially vulnerable to the synergistic effect of loss of β-III spectrin and GLAST.
EAAT4 was downregulated due to the loss of Rheb1 in Purkinje cells; mTORC1 was downregulated and Akt was upregulated in Rheb1 cKO mice, suggesting that mTORC1 and Akt may be related to the downregulation of EAAT4; Rheb1 knockout decreased EAAT4 currents and slowed down the kinetics of AMPA currents; Rheb1 deficiency did not affect the morphology of Purkinje cell layer and the development of Purkinje cells

Purkinje cell loss in the Inpp4a(wbl) mutant is due to glutamate excitotoxicity initiated by the climbing fiber, and that Eaat4 may exert a protective effect.

PF-evoked mGluR-EPSCs showed larger amplitude and faster rising kinetics in EAAT4-deficient mice than in the wild-type mice. EAAT4 is most closely involved in mGluR activation in PCs among the glutamate transporters.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
