Multiple Pathways Regulate Minisatellite Stability During Stationary Phase in Yeast
Alterations in minisatellite DNA repeat tracts in humans have been correlated with a number of serious disorders, including cancer. Despite their importance for human health, the genetic factors that influence minisatellite stability are not well understood. Previously, we identified mutations in the Saccharomyces cerevisiae zinc homeostasis genes ZRT1 and ZAP1 that significantly increase the f...
متن کاملA Whole Genome Screen for Minisatellite Stability Genes in Stationary-Phase Yeast Cells
Repetitive elements comprise a significant portion of most eukaryotic genomes. Minisatellites, a type of repetitive element composed of repeat units 15-100 bp in length, are stable in actively dividing cells but change in composition during meiosis and in stationary-phase cells. Alterations within minisatellite tracts have been correlated with the onset of a variety of diseases, including diabe...
متن کاملZinc regulates the stability of repetitive minisatellite DNA tracts during stationary phase.
Repetitive minisatellite DNA tracts are stable in mitotic cells but unstable in meiosis, altering in repeat number and repeat composition. As relatively little is known about the factors that influence minisatellite stability, we isolated mutations that destabilize a minisatellite repeat tract in the ADE2 gene of Saccharomyces cerevisiae. One mutant class exhibited a novel color segregation phe...
متن کاملStationary phase in yeast.
Eukaryotic cell proliferation is controlled by specific growth factors and the availability of essential nutrients. If either of these signals is lacking, cells may enter into a specialized nondividing resting state, known as stationary phase or G(0). The entry into such resting states is typically accompanied by a dramatic decrease in the overall growth rate and an increased resistance to a va...
متن کاملLength and sequence heterozygosity differentially affect HRAS1 minisatellite stability during meiosis in yeast.
Minisatellites, one of the major classes of repetitive DNA sequences in eukaryotic genomes, are stable in somatic cells but destabilize during meiosis. We previously established a yeast model system by inserting the human Ha-ras/HRAS1 minisatellite into the HIS4 promoter and demonstrated that our system recapitulates all of the phenotypes associated with the human minisatellite. Here we demonst...
