Overview
Mermaid diagram (expand to render)
The GRIA1 gene encodes the GluA1 subunit of the AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) glutamate receptor, a ligand-gated ion channel that mediates fast excitatory synaptic transmission in the brain. AMPA receptors containing the GluA1 subunit are critical for synaptic plasticity, learning, and memory. GRIA1 mutations are associated with neurodevelopmental disorders and epilepsy. [@henley2019]

Learning and memory: Required for hippocampal synaptic plasticity
GRIA1 (Glutamate Ionotropic Receptor AMPA Type Subunit 1) encodes the GluA1 subunit of the AMPA-type glutamate receptor, the primary mediator of fast excitatory synaptic transmission in the mammalian brain. [@liu2021]
Gene Overview
Normal Function
The GRIA1 gene encodes the GluA1 protein subunit, one of four subunits (GluA1-4) that assemble to form AMPA-type ionotropic glutamate receptors. AMPA receptors mediate the majority of fast excitatory neurotransmission in the brain and are critical for:
Synaptic transmission: AMPA receptors conduct Na+ ions to depolarize postsynaptic [neurons](/entities/neurons) following glutamate release
Synaptic plasticity: Activity-dependent changes in AMPA receptor trafficking underlie learning and memory ([LTP](/mechanisms/long-term-potentiation) and LTD)
The study of Gria1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
