A human brain cDNA library constructed in the lambda ZAP II vector was screened using a fragment of pig brain cDNA encoding 4-aminobutyrate aminotransferase (pGaba-t). A cDNA that encodes the human brain Gaba-t (hGaba-t) has been isolated from the library and sequenced. Using the GenBank and EMBL databases, comparison of the predicted amino-acid sequence of hGaba-t with the pig enzyme revealed 95.4% homology.

cDNAs encoding gamma-aminobutyric acid aminotransferase (GABA-T) were isolated from a lambda ZAP rat hippocampal cDNA expression library by two independent cloning methods, immunological screening with an antimouse GABA-T antibody and plaque hybridization with a GABA-T cDNA probe derived by polymerase chain reaction. We have produced enzymatically active GABA-T from a rat brain cDNA containing the full-length GABA-T coding region. Our rat brain GABA-T cDNAs hybridize to mRNAs in brain and peripheral tissues, including liver, kidney, and testis. We have also detected GABA-T mRNA in GABAergic cells of rat cerebellar cortex by in situ hybridization. Our rat brain GABA-T probe hybridizes to Purkinje, basket, stellate, and Golgi II cells, the same GABAergic neurons previously shown to contain glutamate decarboxylase GAD65 and GAD67.
