BACKGROUND The transcription factor B-Myb is present in all proliferating cells, and in mice engineered to remove this gene, embryos die in utero just after implantation due to inner cell mass defects. This lethal phenotype has generally been attributed to a proliferation defect in the cell cycle phase of G1. METHODOLOGY/PRINCIPAL FINDINGS In the present(More)
The Chk2-mediated deoxyribonucleic acid (DNA) damage checkpoint pathway is important for mitochondrial DNA (mtDNA) maintenance. We show in this paper that mtDNA itself affects cell cycle progression. Saccharomyces cerevisiae rho(0) cells, which lack mtDNA, were defective in G1- to S-phase progression. Deletion of subunit Va of cytochrome c oxidase,(More)
Mitochondrial inheritance, the transfer of mitochondria from mother to daughter cell during cell division, is essential for daughter cell viability. The mitochore, a mitochondrial protein complex containing Mdm10p, Mdm12p, and Mmm1p, is required for mitochondrial motility leading to inheritance in budding yeast. We observe a defect in cytokinesis in(More)
