title: Isolation and characterization of the rat gene encoding glutamate dehydrogenase.
abstract: The concentration of glutamate dehydrogenase (GDH) varies strongly between different organs and between different regions within organs. To permit further studies on the regulation of GDH expression, we isolated and characterized the rat gene encoding the GDH protein. This gene contains 13 exons and spans approximately 34 kbp. The GDH gene is present as a single, autosomally located copy in the Wistar rat genome, but shows an extensive restriction-fragment-length polymorphism for several enzymes. Promoter activity of the 5'-flanking sequence is shown by transient transfection experiments. The 5'-flanking sequence contains a TTAAAA sequence at position -29, instead of a consensus TATA box and, like many other TATA-less promoters, is characterized by a very high G + C content. In addition, consensus sequences for the binding sites of the transcription factors Sp1 and Zif268 are present in the G + C-rich upstream region.
