Glutamate Decarboxylase 2 (GAD2) is one of several forms of glutamic acid decarboxylase, identified as a main autoantigen in insulin-dependent diabetes. The GAD2 enzyme is responsible for catalyzing the production of gamma-aminobutyric acid from L-glutamic acid. A pathogenic role for the GAD2 enzyme has been characterized in the human pancreas since it has been identified as an autoantibody and an autoreactive T cell target in insulin-dependent diabetes. GAD2 gene may also have a role in the stiff man syndrome. In addition, GAD2 catalyzes the production of GABA.
Recombinant Human GAD2 produced in SF9 is a biotinylated, glycosylated, polypeptide chain having a calculated molecular mass of 66kDa.
GAD2 is expressed with a 6xHis tag at N-terminus and purified by proprietary chromatographic techniques.
