GLRB (Glycine Receptor Beta Subunit): GLRB is part of the glycine receptor complex, a chloride channel involved in inhibitory neurotransmission in the spinal cord and brainstem. Glycine receptors are critical for motor and sensory functions, and mutations in GLRB can lead to neurological disorders, such as hyperekplexia, which is characterized by an exaggerated startle response. Understanding GLRB's role in neurotransmission provides insights into the mechanisms underlying inhibitory pathways and associated disorders....
