Background

Glutamate decarboxylase is a member of thegroup II decarboxylase family. GAD2 is identified as a major autoantigen in insulin-dependent diabetes. It is responsible for catalyzing the production of gamma-aminobutyric acid from L-glutamic acid.GAD2 also is implicated in the formation of the gamma-aminobutyric acid (GABA), a neurotransmitter involved in the regulation of food intake and play a role in the stiff man syndrome.
