title: Rat copper/zinc superoxide dismutase gene: isolation, characterization, and species comparison.
abstract: A 13 kb rat Cu/ZnSOD genomic clone has been purified from a rat liver genomic library and completely characterized by restriction mapping, detailed sequencing and Southern blot analysis. This gene spans approximately 6 kb and contains five exons and four introns. Comparison of rat, mouse, and human Cu/ZnSOD genes reveals a high conservation in genomic organization and exon-intron junctions, including an unusual 5'GC donor sequence at the first intron. The gene contains a TATA box as well as an inverted CCAAT box, a feature common to both the mouse and human genes. Furthermore, several repeats were identified in the 5' promoter region of this gene, and these regulatory elements are also strikingly conserved in these three species.
