Mitochondrially-targeted APOBEC1 is a potent mtDNA mutator affecting mitochondrial function and organismal fitness in Drosophila

Abstract

The role of mitochondrial DNA mutations in organismal fitness and lifespan have been studied in mitochondrial mutator models with varying results. Here, the authors generate a new APOBEC1 expression-based Drosophila mutator model and show that it has limited mitochondrial function and reduced lifespan.
