Other Information

**Key Characteristics:** 1. **GABA-A Receptor Subunit Gamma2:** GABRG2 is a subunit of the GABA-A receptor, which is a ligand-gated chloride channel complex that plays a crucial role in regulating neuronal excitability and synaptic transmission. 2. **Significant Expression in Neuronal Populations:** GABRG2 is expressed in various neuronal populations, including inhibitory interneurons, pyramidal neurons, and GABAergic cortical interneurons, highlighting its widespread involvement in neural circuitry. 3. **Involvement in Synaptic Transmission:** The GABRG2 gene is involved in regulating synaptic transmission across chemical synapses, which is essential for maintaining proper neuronal function and behavior. 4. **Benzodiazepine Receptor Activity:** GABRG2 is also involved in benzodiazepine receptor activity, which is a key mechanism for regulating GABAergic neurotransmission and promoting anxiolytic and sedative effects. **Pathways and Functions:** 1. **GABAergic Signaling Pathway:** GABRG2 is a key component of the GABAergic signaling pathway, which is responsible for regulating neuronal excitability and synaptic transmission. 2. **Chloride Channel Activity:** GABRG2 is a chloride channel subunit that plays a critical role in regulating chloride ion flow across the postsynaptic membrane, which is essential for modulating neuronal excitability and synaptic transmission. 3. **Regulation of Postsynaptic Membrane Potential:** The GABRG2 gene is involved in regulating postsynaptic membrane potential, which is critical for maintaining proper neuronal function and behavior. 4. **Inhibitory Synapse Assembly:** GABRG2 is involved in inhibitory synapse assembly, which is essential for regulating synaptic transmission and neuronal excitability. **Clinical Significance:** 1. **Neurological Disorders:** Alterations in GABRG2 expression have been implicated in various neurological disorders, including epilepsy, anxiety disorders, and schizophrenia. 2. **Anxiolytic and Sedative Effects:** GABRG2 is involved in benzodiazepine receptor activity, which is a key mechanism for regulating GABAergic neurotransmission and promoting anxiolytic and sedative effects. 3. **Neurodevelopmental Disorders:** GABRG2 is also involved in neurodevelopmental disorders, including autism spectrum disorder and attention-deficit/hyperactivity disorder (ADHD). 4. **Cancer Therapy:** GABRG2 has been identified as a potential target for cancer therapy, as it is involved in regulating tumor cell growth and proliferation. In conclusion, the gamma-aminobutyric acid type A receptor subunit gamma2 (GABRG2) gene plays a critical role in modulating neural synaptic transmission and behavior. Its significant expression in various neuronal populations and involvement in GABAergic signaling pathway, chloride channel activity, and regulation of postsynaptic membrane potential highlight its importance in maintaining proper neuronal function and behavior. Further research is needed to fully elucidate the clinical significance of GABRG2 and its potential applications in treating various neurological and cancer disorders.
