Gabrg2 Protein — Gaba A Receptor Gamma2 Subunit is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The GABA-A receptor gamma2 subunit is essential for synaptic receptor localization and function. The gamma2 subunit is the most common auxiliary subunit in synaptic GABA-A receptors, forming complexes with α and β subunits to create the characteristic pentameric structure. This subunit contains a long cytoplasmic loop between transmembrane domains 3 and 4 that mediates interactions with gephyrin, the primary scaffold protein at inhibitory synapses. Receptors containing the γ2 subunit are benzodiazepine-sensitive and mediate the majority of phasic inhibition in the brain.
