      Alternate Names
      • Glutamate decarboxylase 1
      • 67 kDa glutamic acid decarboxylase
      • GAD-67
      • Glutamate decarboxylase 67 kDa isoform
      Background InformationGutamic acid decarboxylase (GAD; E.C. 4.1.1.15) 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 (65 kDa and 67 kDa, 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, 1999). GAD65 is an amphiphilic, membrane-anchored protein (585 a.a.), encoded on human chromosome 10, and is responsible for vesicular GABA production. GAD67 is cytoplasmic (594 a.a.), encoded on chromosome 2, and seems to be responsible for significant cytoplasmic GABA production. 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, 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, 1995). GAD67 expression seems to be particularly plastic and can change in response to experimental manipulation (for example neuronal stimulation or transection) or disease progression and emergent disorders like schizophrenia (Volk, 2000). Colocalization of the two GAD isoforms also shows changes in GAD65/GAD67 distributions correlated with certain disease states such as IDDM and SMS.

      UniProt SummaryFUNCTION: Catalyzes the production of GABA.

      CATALYTIC ACTIVITY: L-glutamate = 4-aminobutanoate + CO2.

      COFACTOR: Pyridoxal phosphate.

      SUBUNIT STRUCTURE: Homodimer.

      TISSUE SPECIFICITY: Isoform 3 is expressed in pancreatic islets, testis, adrenal cortex, and perhaps other endocrine tissues, but not in brain.

      INVOLVEMENT IN DISEASE: Defects in GAD1 are the cause of cerebral palsy spastic quadriplegic type 1 (CPSQ1) [MIM:603513]. A non-progressive disorder of movement and/or posture resulting from defects in the developing central nervous system. Affected individuals manifest symmetrical, non-progressive spasticity and no adverse perinatal history or obvious underlying alternative diagnosis. Developmental delay, mental retardation and sometimes epilepsy can be part of the clinical picture.

      SEQUENCE SIMILARITIES: Belongs to the group II decarboxylase family.
      Molecular Weight~67 kDa.
