Description générale

GAD 65 has been identified as an autoantigen in insulin dependent diabetes mellitus (IDDM) and stiff-man syndrome (SMS).
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. 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. 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.

Spécificité

Reacts specifically with GAD 65 and GAD 67 isoforms from brain.
Reacts specifically with GAD 65 and GAD 67 isoforms in extracts of rat brain and rat pancreas.

Immunogène

synthetic peptide corresponding to the C-terminal region of human GAD 67 (amino acids 579-594). The sequence is identical in human GAD 65 (amino acids 570-585), in rat, mouse, and pig GAD 65, in rat, pig, and cat GAD 67, and is highly conserved in GAD 67 of mouse origin (single amino acid substitution).

Application

Anti-GAD 65/67 may be used for the detection and localization of GAD 65/67 isoforms by immunofluorescence and immunohistochemistry in rat retinal cells, human subthalamus neurons, and pancreatic β-cells of rat. The minimum working dilution that may be used is 1:10000. Detection by immunoblotting may be possible in brain cells of monkey, human, rat and gecko. at a minimum working dilution of 1:1000.
Anti-Glutamic Acid Decarboxylase 65/67 antibody produced in rabbit has also been used in Immunohistochemistry and Immunocytochemistry.

Actions biochimiques/physiologiques

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).

Glutamate decarboxylase (GAD) is an enzyme that synthesizes gamma-aminobutyrate (GABA), a major inhibitory neurotransmitter in the central nervous system. Post-translational modification of GAD, such as N-terminal blockage, phosphorylation-dephosphorylation, and palmitoylation, is an important factor in the biological activity of GAD.
