Introduction
Glutamate Decarboxylase 1 Isoform-1, also known as GAD1 iso1 belongs to
the group II decarboxylase family. GAD1 iso1 encodes one of several forms of
glutamic acid decarboxylase, and is identified as a major autoantigen in
insulin-dependent diabetes. GAD1 iso1 is in charge for catalyzing the
production of gamma-aminobutyric acid from L-glutamic acid. In addition, a
pathogenic function for GAD1 iso1 has been shown in the human pancreas while it
has been identified as an autoantigen & an autoreactive T cell target in
insulin-dependent diabetes. GAD1 iso1 play a role in the stiff man syndrome. It
has been shown that deficiency in this enzyme has led to pyridoxine dependency
with seizures.
Description
GAD1 iso1 Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 617 amino acids (1-594 a.a) and
having a molecular mass of 69.3kDa.
GAD1 iso1 is fused to a 23 amino acid His-tag at
N-terminus & purified by proprietary chromatographic techniques.
Source
E.coli.
