Summary
The protein encoded by this gene is an enzyme that catalyzes the production of gamma-aminobutyric acid from L-glutamic acid. Alternative splicing of this gene results in three products, the predominant 67 kDa isoform, a smaller 25 kDa isoform, and an even smaller 49 aa isoform. The two shorter isoforms are not thought to retain catalytic activity. [provided by RefSeq, Apr 2023]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
