Enzymatic studies of DNA repair in Drosophila melanogaster

Abstract

Thus far, our studies in Drosophila have concentrated primarily on the various enzymes involved in the in vitro repair of modified or nonconventional DNA substrates. In some cases, our findings have led us to investigate events that may not have a bearing on DNA repair, but rather may be associated with developmental signals important to the maturation of the organism. As appealing as some of these models seem, however, they must await confirmation through detailed genetic studies before any substantial conclusions can be drawn. This combination of genetic and biochemical knowledge makes Drosophila an exciting organism for an eventual detailed understanding of the developmental expression and cellular location of DNA-repair systems.
