Mitochondrial morphology and function depend on MGM1, a Saccharomyces cerevisiae gene encoding a dynamin-like protein of the mitochondrial outer membrane. Here, we show that mitochondrial fragmentation and mitochondrial genome loss caused by lesions in MGM1 are suppressed by three novel mutations, gag1, gag2, and gag3 (for glycerol-adapted growth).

The mdm17 mutation causes temperature-dependent defects in mitochondrial inheritance, mitochondrial morphology, and the maintenance of mitochondrial DNA in the yeast Saccharomyces cerevisiae. Defects in mitochondrial transmission to daughter buds and changes in mitochondrial morphology were apparent within 30 min after shifting cells to 37 degrees C, while(More)
Cytoplasmic mRNA localization provides a means of generating cell asymmetry and segregating protein activity. Previous studies have identified two mRNAs that localize to the bud tips of the yeast Saccharomyces cerevisiae. To identify additional localized mRNAs, we immunoprecipitated the RNA transport components She2p, She3p, and Myo4p and performed DNA(More)
Cytoplasmic mRNA localization is a mechanism used by many organisms to generate asymmetry and sequester protein activity. In the yeast Saccharomyces cerevisiae, mRNA transport to bud tips of dividing cells is mediated by the binding of She2p, She3p, and Myo4p to coding regions of the RNA. To date, 24 bud-localized mRNAs have been identified, yet the RNA(More)
Mgm1p is a conserved dynamin-related GTPase required for fusion, morphology, inheritance, and the genome maintenance of mitochondria in Saccharomyces cerevisiae. Mgm1p undergoes unconventional processing to produce two functional isoforms by alternative topogenesis. Alternative topogenesis involves bifurcate sorting in the inner membrane and intramembrane(More)
Efforts have emerged internationally to recruit donors with specific disease indications and to derive induced pluripotent cell lines. These disease-specific induced pluripotent stem cell lines have the potential to accelerate translational goals such as drug discovery and testing. One consideration for donor recruitment and informed consent is the(More)
The mdm17 mutation causes temperature-dependent defects in mitochondrial inheritance, mito-chondrial morphology, and the maintenance of mito-chondrial DNA in the yeast Saccharomyces cerevisiae. Defects in mitochondrial transmission to daughter buds and changes in mitochondrial morphology were apparent within 30 min after shifting cells to 37 Њ C, while loss(More)
