Molecular cloning, expression and in situ hybridization of rat brain glutamic acid decarboxylase messenger RNA.
A cDNA library was generated in the expression vector lambda GT11 from rat brain poly(A)+ RNAs and screened with a GAD antiserum. Two clones reacted positively. One of them was shown to express a GAD activity which was specifically trapped on anti-GAD immunogel and was inhibited by gamma-acetylenic-GABA. Blot hybridization analysis of RNAs from rat brain revealed a single 4 kilobases band. Preliminary in situ hybridizations showed numerous cells labelled by the GAD probe such as the Purkinje and stellate cells in the cerebellar cortex and the cells of the reticular thalamic nucleus.
