Other Information

**Key Characteristics** 1. **Transmembrane Protein**: GABRB2 is a transmembrane protein that spans the plasma membrane, interacting with other subunits to form functional GABA-A receptors. 2. **Inhibitory Neurotransmission**: GABRB2 plays a critical role in regulating inhibitory neurotransmission, which is essential for maintaining neuronal excitability and preventing excessive neuronal firing. 3. **GABA-A Receptor Complex**: GABRB2 is a component of the GABA-A receptor complex, which assembles with other subunits to form functional receptors. 4. **Widespread Expression**: GABRB2 is expressed in various brain regions, including the cerebral cortex, hippocampus, and cerebellum. 5. **Cell Type-Specific Expression**: GABRB2 is significantly expressed in Purkinje cells, macroglial cells, and different types of cortical interneurons. **Pathways and Functions** 1. **GABA Signaling Pathway**: GABRB2 is involved in the GABA signaling pathway, which regulates inhibitory neurotransmission and neuronal excitability. 2. **Inhibitory Synapse Assembly**: GABRB2 plays a role in the assembly of inhibitory synapses, which are essential for regulating neuronal communication. 3. **Regulation of Membrane Potential**: GABRB2 regulates the membrane potential of neurons by modulating the activity of chloride channels. 4. **Signaling by Receptor Tyrosine Kinases**: GABRB2 interacts with receptor tyrosine kinases to regulate signaling pathways involved in neuronal development and plasticity. 5. **Transmembrane Transport**: GABRB2 is involved in transmembrane transport, regulating the movement of ions across the plasma membrane. **Clinical Significance** 1. **Neurological Disorders**: Alterations in GABRB2 expression have been implicated in various neurological disorders, including epilepsy, anxiety disorders, and schizophrenia. 2. **Neurodevelopmental Disorders**: GABRB2 has been linked to neurodevelopmental disorders, such as autism spectrum disorder and intellectual disability. 3. **Neuropsychiatric Disorders**: GABRB2 has been implicated in neuropsychiatric disorders, including bipolar disorder and major depressive disorder. 4. **Neuroprotection**: GABRB2 has been shown to have neuroprotective effects, regulating neuronal excitability and preventing excitotoxicity. 5. **Therapeutic Potential**: Targeting GABRB2 has potential therapeutic implications for the treatment of neurological and neuropsychiatric disorders. In conclusion, GABRB2 is a critical gene involved in regulating inhibitory neurotransmission and neuronal excitability. Its widespread expression and cell-type-specific expression patterns make it an attractive target for therapeutic interventions in various neurological and neuropsychiatric disorders.
