GAD is highly expressed in GABAergic neurons and pancreatic β cells. It is transiently expressed in non-GABAergic embryonic and adult neurons, indicating a role in development. It is also present in testis, oviduct, and ovary GAD exists as two isoforms, GAD 65 and GAD 67 (molecular masses of 65 and 67 kDa, respectively) that are encoded by two different genes.ENCE ID="150851" TYPE="literature"/>ENCE ID="150852" TYPE="literature"/> GAD65 is an ampiphilic, membrane anchored protein, (585 amino acid residues) and is encoded on human chromosome 10. GAD 67 is a cytoplasmic protein (594 amino acid residues) and is encoded on chromosome 2. There is 64% amino acid idENTITY_TYPE_CODE. The two isoforms appear to have distinct intraneuronal distribution in the brain.ENCE ID="1044038" TYPE="literature"/> The protein is initially localized to cytosol and then gets anchored to the membrane upon post translational modification. The GAD2 gene is mapped to human chromosome 10p12.1.

Application: Anti-Glutamic Acid Decarboxylase 65/67 antibody produced in rabbit has also been used in Immunohistochemistry and Immunocytochemistry.
Biochem Physiol Actions: Glutamic acid decarboxylase (GAD) is the key enzyme that catalyses the conversion of L-glutamate to γ-aminobutyric acid (GABA). GABA is a principal inhibitory neurotransmitter and a paracrine signal molecule in pancreatic islet cells. GAD 65 has been identified as an autoantigen in insulin dependent diabetes mellitus (IDDM) and stiff-man syndrome (SMS).
