GRM1 (Glutamate Receptor, Metabotropic 1): GRM1 is a receptor for glutamate, the primary excitatory neurotransmitter in the nervous system. It plays a key role in regulating synaptic plasticity, learning, and memory. GRM1 is involved in multiple neural pathways and has been linked to neurological and psychiatric disorders such as epilepsy, schizophrenia, and neurodegenerative diseases. Its function in neurotransmission and brain activity makes it a promising target for therapeutic interventions in these conditions.
