General description

GAD is predominantly expressed in the central nervous system (CNS) and pancreatic islets. It is also expressed in testis, oviduct and ovary. GAD exists in two isofoms, GAD 65 and GAD 67. GAD65 is targeted to membranes and nerve endings.

Specificity

Reacts specifically with GAD 65 (65 kDa).

Immunogen

synthetic peptide corresponding to the N-terminal region of human GAD 65 (amino acids 5-22). The sequence is highly conserved in rat and pig GAD 65 (single amino acid substitution) and mouse and monkey GAD 65, but is not found in GAD 67.

Application

Anti-Glutamic Acid Decarboxylase 65 (5-22) antibody produced in rabbit has been used in immunohistochemistry and immunocytochemistry.

Biochem/physiol Actions

Glutamic Acid Decarboxylase (GAD) catalyzes the conversion of L-glutamate to γ-aminobutyric acid (GABA), the principal inhibitory neurotransmitter in the brain, and a putative paracrine signal molecule in pancreatic islets. GAD65 is an ampiphilic, membrane-anchored protein, (585 amino acid residues) and is encoded on human chromosome 10. It has been identified as an autoantigen in insulin-dependent diabetes mellitus (IDDM) and stiff-man syndrome (SMS) and may serve as a marker in the early stages of IDDM. GAD 65 synthesizes transmitter GABA for vesicular release.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Studies of the GABA-synthetic enzyme glutamate decarboxylase (glutamic acid decarboxylase; GAD; E.C.4.1.1.15) began in 1951 with the work of Roberts and his colleagues. Since then, many investigators have demonstrated the structural and functional heterogeneity of brain GAD. At least part
