GRIA1: GRIA1 is a gene that encodes a key subunit of AMPA receptors, which are essential for fast synaptic transmission in the brain. These receptors respond to glutamate, the primary excitatory neurotransmitter in the nervous system. The GRIA1 subunit plays a vital role in synaptic plasticity, which underlies learning and memory. Alterations or mutations in GRIA1 have been linked to neurological disorders such as epilepsy and neurodegenerative diseases, making it an important target in neuroscience research.
