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 an ampiphilic, membrane-anchored protein, (585 amino acid residues) and is encoded on human chromosome 10.

Specificity

Reacts specifically with GAD 65 (65 kDa) from brain.

Immunogen

synthetic peptide corresponding to the C-terminal region of human GAD 65 (amino acids 514-530). The sequence is identical in mouse GAD 65 and highly conserved in rat and pig GAD 65 but not found in GAD 67.

Application

Anti-Glutamic Acid Decarboxylase 65 antibody produced in rabbit is suitable as a primary antibody for the determination of expression of GAD 65 isoform in putative P boutons in rat and mouse at a working dilution of 1:5000 and in lysates prepared from rat testis at different developmental ages and rat cerebellum by immunoblotting.
It is also suitable for immunohistochemistry at a working dilution of 1:500 using formalin-fixed, paraffin-embedded sections of rat pancreas and for microarray.

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. 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.

Human peripheral blood leucocyte was examined for the expression of glutamate decarboxylase (GAD). Peripheral blood from healthy individuals was fractionated into polynuclear leucocytes and mononuclear leucocytes. Cell lysate from the mononuclear leucocytes was analysed by SDS-PAGE and Western blot. With

Glutamate decarboxylase 65 (GAD65) produces gamma-aminobutyric acid, the main inhibitory neurotransmitter in adult mammalian brain. Previous experiments, performed in brain, showed that GAD65 gene possesses two TATA-less promoters, although the significance is unknown. Here, by rapid amplification of cDNA ends

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
