Description Glutamate decarboxylase. (family a)
Notes This family encompasses exclusively metazoan glutamate decarboxylase sequences.
Two isoforms of glutamate decarboxylase, encoded by different genes, occur in mammalian tissues: a 67-kDa form (DCE1 or GAD67) and a 65-kDa form (DCE2 or GAD65).
Alternate splicing produces smaller variants of GAD67 in the brain of mice and rat embryos. Another splice variant of GAD67 (termed GAD25 and devoid of GAD enzymatic activity) is produced in human islets, testis and adrenal cortex.
