Summary: Predicted to enable glutamate binding activity; glutamate decarboxylase activity; and pyridoxal phosphate binding activity. Predicted to be involved in gamma-aminobutyrate shunt and gamma-aminobutyric acid biosynthetic process. Located in axon; cytoplasm; and synapse. Is expressed in several structures, including central nervous system; genitourinary system; gut; heart; and sensory organ. Used to study epilepsy and type 1 diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; amphetamine abuse; diabetes mellitus (multiple); drug psychosis; and heroin dependence. Orthologous to human GAD2 (glutamate decarboxylase 2). [provided by Alliance of Genome Resources, Jul 2025]
Expression: Biased expression in frontal lobe adult (RPKM 14.3), whole brain E14.5 (RPKM 8.4) and 5 other tissues See more

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.
