L., Wang, Y., and Kaguni, L. S. (1999) J. Biol. Chem. 274, 14779-14785). We show here that DNA-binding mutants of mtSSB are defective in stimulation of DNA synthesis by pol gamma. RNAi knock-down of mtSSB reduces expression to <5% of its normal level in Schneider cells, resulting in growth defects and in the depletion of mitochondrial DNA (mtDNA). Overexpression of mtSSB restores cell growth rate and the copy number of mtDNA, whereas overexpression of a DNA-binding and functionally impaired form of mtSSB neither rescues the cell growth defect nor the mtDNA depletion phenotype. Further development of Drosophila animal models, in which induced mtDNA depletion is manipulated by controlling exogenous expression of wild-type or mutant forms, will offer new insight into the mechanism and progression of human mtDNA depletion syndromes and possible intervention schemes."xsd:string |
