About GABRA2

Cytogenetic location: 4p12 Genomic coordinates (GRCh38): 4:46,243,548-46,390,300 (from NCBI)

This gene has 16 transcripts (splice variants), 256 orthologues, 45 paralogues and is associated with 3 phenotypes. Biased expression in brain (RPKM 13.5), kidney (RPKM 1.1) and 1 other tissue.

Summary

GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]
