GAD67, a 67 kDa protein, is a neuronal isoform of this enzyme predominantly expressed in human Brain. It consists of Pyridoxal 5-phosphate binding site and conserved Cysteine residues which are vital for its activity and is inhibited due to phosphorylation. It has high binding affinity for the cofactor Pyridoxal-5phosphate and its role has been implicated in normal Palate development. It is found to be associated with childhood onset schizophrenia and craniofacial malformations and has been identified as a major auto antigen and an auto-reactive T-cell target in IDDM. Deficiency of this enzyme leads to pyridoxine dependency along with epilepsy. It also might play a role in stiff main syndrome.
GAD1 antibody can be used in ELISA, Western Blot, and immunohistochemistry starting at 5 μg/mL.
