Entrez Gene Summary for GABRG1
The protein encoded by this gene belongs to the ligand-gated ionic channel family. It is an integral membrane protein and plays an important role in inhibiting neurotransmission by binding to the benzodiazepine receptor and opening an integral chloride channel. This gene is clustered with three other family members on chromosome 4. (provided by RefSeq, Jul 2008)

UniProtKB Summary for GABRG1
Function: GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel

Tocris Summary for GABRG1
GABAA receptors are members of the cys-loop family of ligand-gated ion channels, responsible for mediating the inhibitory effects of GABA alongside GABAB and GABAC receptors. They are pentameric proteins, consisting of 5 subunits belonging to different families (alpha1-6, beta1-3, gamma1-3, delta, pi, epsilon, rho, theta). The most abundant GABAA receptor in the mammalian brain consist of two copies each of alpha1 and beta2 with a single gamma2 subunits. GABAA receptors contain an integral chloride channel, and have modulatory sites for benzodiazepines, barbiturates, neurosteroids and ethanol.
