Glutamic acid decarboxylase (GAD; E.C. 18.104.22.168) is the enzyme responsible for the conversion of glutamic acid to gamma-aminobutyric acid (GABA), the major inhibitory transmitter in higher brain regions, and putative paracrine hormone in pancreatic islets. Two molecular forms of GAD (65kD and 67kD, 64% aa identity between forms) are highly conserved and both forms are expressed in the CNS, pancreatic islet cells, testis, oviduct and ovary. The isoforms are regionally distributed cytoplasmically in the brains of rats and mice (Sheikh, S. et al. 1999). GAD65 is an ampiphilic, membrane-anchored protein (585aa) encoded on human chromosome10. GAD67 is cytoplasmic (594aa) and is encoded on chromosome 2. GAD expression changes during neural development in rat spinal cord. GAD65 is expressed transiently in commissural axons around E13 but is down regulated the next day while GAD67 expression increases mostly in the somata of those neurons (Phelps, P. et al. 1999). In mature rat pancreas, GAD65 and GAD67 appear to be differentially localized, GAD65 primarily in insulin-containing beta cells and GAD67 in glucagon-containing (A) cells (Li, L. et al. 1995). Changes in GAD65/GAD67 distributions have also been correlated with certain disease states such as IDDM and SMS.
Immunogen: Synthetic peptide corresponding to DFLIEEIERLGQDL from the C-terminus of rat GAD. In general, we may offer more than one antibody to a given target to enable options for the researcher. Available antibodies recognizing GAD2 are readily searchable from our website. Different antibodies against the same target such as GAD2 may be optimized or tested for different applications and species. This enables researchers to select the option that may be best for their model system, to screen more than antibody to determine which one may be best for their model system, as well as to use more than one antibody to follow up on and validate their results.
