  1. 16. Insights into the roles of the essential Pfh1 DNA helicase in the nuclear and mitochondrial genomes

    Författare :Parham Pourbozorgi Langroudi; Nasim Sabouri; Anders Hofer; Per Sunnerhagen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; G4; genome integrity; Pfh1; Top1; helicase; topoisomerase; replication; transcription;

    Sammanfattning : Eukaryotic cells have two sets of genomes, the nuclear and mitochondrial, and both need to be accurately maintained. Also, the rate of transcription must be precisely regulated in these genomes. However, there are many natural barriers that dysregulate these processes. LÄS MER

  3. 17. Chromatin remodelers and their roles in chromatin organization

    Författare :Annelie Strålfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The DNA in the eukaryotic nucleus is organized into a complex DNA-protein structure called chromatin. The basic repeating unit of chromatin is the nucleosome, which consists of 147 bp of DNA wrapped around a histone protein octamer. LÄS MER

  4. 18. Characterization of RNA polymerase II subunit Rpb7 in silencing and transcription

    Författare :Ingela Djupedal; Karl Ekwall; Anthony Wright; Olivier Voinnet; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The DNA in eukaryotes is arranged in fibres of chromatin. The chromatin may be more or less compacted and the degree of condensation of the chromatin affects the accessibility of the DNA. The accessibility of the DNA, in turn, affects transcription and gene regulation. LÄS MER

  5. 19. The Saccharomyces cerevisiae MAPKAP kinases Rck1 and Rck2 in stress responses

    Författare :Elizabeth Bilsland; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The Saccharomyces cerevisiae protein kinases Rck1 and Rck2 (Radiation sensitivity Complementing Kinases) were originally cloned as suppressors of Schizosaccharomyces pombe checkpoint mutants. In Saccharomyces cerevisiae we found that overexpression of either kinase has the ability to depress sporulation in mec1 and rad24 mutant backgrounds. LÄS MER

  7. 20. Modulating chromatin by transcription and nucleosome turnover : a genome-wide study in fission yeast

    Författare :Laia Sadeghi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Eukaryotic DNA is wrapped around histone proteins to form a nucleosome, the basic structural unit of chromatin. Multiple levels of chromatin organization are required to compact DNA into chromosomes, to ensure an accurate cell division. LÄS MER
