NameDmp53
OrganismDrosophila melanogaster
Aging PhenotypeLife-span extension
Allele TypeOverexpression
Strainmultiple backgrounds
DescriptionExpression of a dominant-negative allele of dmp53 specifically in adult neurons increases life-span by approximately 15% in flies (Bauer et al., 2005)
Gene FunctionOrtholog of a mammalian tumor suppressor.
Other PhenotypesLife-span extension by expression of DN-dmp53 is not additive with life-span extension from calorie restriction.
