Genetic basis of mitochondrial function and morphology in Saccharomyces cerevisiae.
The understanding of the processes underlying organellar function and inheritance requires the identification and characterization of the molecular components involved. We pursued a genomic approach to define the complements of genes required for respiratory growth and inheritance of mitochondria with normal morphology in yeast. With the systematic screening of a deletion mutant library coverin...
متن کاملTwo Distinct Vps34 Phosphatidylinositol 3–Kinase Complexes Function in Autophagy and Carboxypeptidase Y Sorting inSaccharomyces cerevisiae
Vps30p/Apg6p is required for both autophagy and sorting of carboxypeptidase Y (CPY). Although Vps30p is known to interact with Apg14p, its precise role remains unclear. We found that two proteins copurify with Vps30p. They were identified by mass spectrometry to be Vps38p and Vps34p, a phosphatidylinositol (PtdIns) 3-kinase. Vps34p, Vps38p, Apg14p, and Vps15p, an activator of Vps34p, were coimm...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولMitochondrial DNA ligase function in Saccharomyces cerevisiae.
The Saccharomyces cerevisiae CDC9 gene encodes a DNA ligase protein that is targeted to both the nucleus and the mitochondria. While nuclear Cdc9p is known to play an essential role in nuclear DNA replication and repair, its role in mitochondrial DNA dynamics has not been defined. It is also unclear whether additional DNA ligase proteins are present in yeast mitochondria. To address these issue...
متن کاملMaintenance of mitochondrial morphology is linked to maintenance of the mitochondrial genome in Saccharomyces cerevisiae.
In the yeast Saccharomyces cerevisiae, certain mutant alleles of YME4, YME6, and MDM10 cause an increased rate of mitochondrial DNA migration to the nucleus, carbon-source-dependent alterations in mitochondrial morphology, and increased rates of mitochondrial DNA loss. While single mutants grow on media requiring mitochondrial respiration, any pairwise combination of these mutations causes a re...
