Other Information

**Key characteristics:** - GRM5 is a member of the glutamate receptor family of ion channels. - It is a G protein-coupled receptor, meaning that it couples to G proteins, which are signaling molecules that transmit signals from the receptor to other cellular components. - GRM5 is expressed in a variety of brain regions, including inhibitory interneurons, neurons, and pyramidal neurons. - It is particularly abundant in inhibitory interneurons, where it is involved in regulating synaptic plasticity and learning and memory processes. **Pathways and functions:** - GRM5 is primarily expressed on the surface of neurons and is a ligand for the neurotransmitter glutamate. - Upon binding to glutamate, GRM5 undergoes conformational changes that allow it to interact with G proteins. - The binding of G proteins to GRM5 activates them, leading to the closure of ligand-gated ion channels and the depolarization of the neuron. - This change in membrane potential can either inhibit or excite postsynaptic neurons, depending on the context. - GRM5 is also involved in regulating calcium signaling, as it can interact with calcium channels and modulate their activity. **Clinical significance:** - Mutations in GRM5 have been linked to several neurological disorders, including autism, schizophrenia, and epilepsy. - In particular, GRM5 mutations are thought to be involved in the pathogenesis of autism spectrum disorder (ASD), a neurodevelopmental disorder characterized by social and communication deficits. - Genetic studies have identified GRM5 as a potential therapeutic target for ASD, as it is highly expressed in the brain regions implicated in the disease. - Drugs that block GRM5 activity have shown promise in preclinical models of ASD, suggesting that targeting this receptor could be a potential therapeutic strategy for this disorder.
