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