Gamma-aminobutyric acid-gated chloride channel (GABA_A receptor)

Target
GABA_A receptor
Molecular classification
Ligand-gated ion channel, Ionotropic receptor
01

Overview

The GABA_A receptor is a ligand-gated chloride channel that mediates fast synaptic inhibition in the central nervous system. It is a pentameric protein composed of various subunits, resulting in diverse receptor isoforms with distinct pharmacological properties. The receptor is a major target for anxiolytic, sedative, and anticonvulsant drugs.
