  2. 1. The maintenance of telomeres in the budding yeast Naumovozyma castellii

    Author : Humberto Itriago; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Telomere; Telomere dynamics; Telomere-Binding Proteins; Cdc13; Rap1; RAD52; Rad51; Homologous recombination; ALT; Budding yeast; Naumovozyma castellii;

    Abstract : Linear chromosomes of eukaryotic cells require the presence of functional nucleoprotein terminal structures, known as telomeres, to protect the integrity of the genome. The telomere is a highly dynamic and regulated structure constituted by short tandem DNA repeats rich in guanine nucleotides that extent as double-stranded DNA ending in a single-stranded 3′ overhang.

  4. 2. RAP1 at the Yeast Telomere

    Author : Johan Wahlin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; DNA-binding; Saccharomyces; yeast; telomeric repeat; telomere; RAP1; repressor activator protein 1; Genetics; cytogenetics; Genetik;

    Abstract : Telomeres are specialized complexes of DNA and proteins that cap and confer stability to the ends of eukaryotic chromosomes. The telomeric DNA of most eukaryotes is composed of tandemly arranged short repeats. Within the budding yeasts these repeats are diverged in length as well as in nucleotide composition. READ MORE

  5. 3. Silencing and DNA double-strand break repair in budding yeast

    Author : Andreas Kegel; Stefan Åström; Stephan Marcand; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silencing; Reb1; DSB; NHEJ; Nej1; illegitimate recombination; yeast; Developmental biology; Utvecklingsbiologi;

    Abstract : Transcriptional silencing that makes large chromosomal domains inaccessible for the transcriptional apparatus is nucleated at DNA elements called silencers. In K.lactis a 102bp HMLα silencer was defined revealing three distinct protein-binding regions (A, B, and C) that were required for silencing of HMLα. READ MORE

  6. 4. Studies of Budding Yeast Transcription Factors Acting Downstream of Nutrient Signaling Pathways

    Author : Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Budding yeast; nutrient signaling; glucose repression; aging; caloric restriction; JmjC; histone demethylation; Mig1; Mig2; Mig3; Gis1; Rph1; Molekylär genetik; Molecular Genetics;

    Abstract : Being able to respond to extracellular cues such as nutrients and growth factors is of vital importance to all living cells. Pathways have therefore evolved which can sense the extracellular status, transmit a signal through the cell and affect gene expression, which ultimately enables adaptation. READ MORE

  7. 5. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Author : Kristofer Bodvard; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Abstract : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. READ MORE
