  1. 1. Function and regulation of the Yeast Mig1 repressor

    Författare :Jonas Östling; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; glucose repression; Mig1; zinc finger protein; Saccharomyces cerevisiae; Kluyveromyces marxianus; Snf1; Biokemi; Biochemistry; Biokemi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Glucose repression is a global regulatory response in the yeast Saccharomyces cerevisiae. Thus, in the presence of glucose, the preferred carbon source, expression of many genes encoding proteins required for metabolism of other carbon sources are turned off.An important mediator of glucose repression is the Mig1 repressor.

  3. 2. Dynamic regulation of the Mig1 transcriptional repressor under glucose de/repression

    Författare :Sviatlana Shashkova; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cell signalling; glucose repression; Mig1; phosphorylation; Saccharomyces cerevisiae;

    Sammanfattning : The budding yeast Saccharomyces cerevisiae AMP-activated protein kinase/SNF1 is a member of a highly conserved protein family present in all eukaryotes. Snf1 regulates energy homeostasis; in yeast, it is best-known for its role in cellular adaptation to glucose limitation. LÄS MER

  4. 3. Dynamic control of the yeast AMPK/SNF1 pathway in response to glucose signals

    Författare :Loubna Bendrioua; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AMPK; SNF1; Mig1; glucose signalling; dynamic control; mechanism; Saccharomyces cerevisiae;

    Sammanfattning : The SNF1/AMP-activated protein kinase (AMPK) belongs to a family of energy sensors that is conserved in all eukaryotes. Activated by ATP depletion, AMPK plays a vital role in restoring the energy balance by enhancing energy-generating and damping energy-requiring processes. LÄS MER

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

    Författare :Niklas Nordberg; Hans Ronne; Anders Blomberg; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 5. The Role of Hexose Transport on Glycolytic Flux and Glucose Induced Responses in Saccharomyces cerevisiae

    Författare :Karin Elbing; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; glucose signaling; metabolic control; Snf1; glycolysis; Mig1; Hexose transport; Yeast; Saccharomyces cerevisiae;

    Sammanfattning : In the yeast Saccharomyces cerevisiae, glucose is primarily fermented rather than respired. Only in cultivation modes such as chemostats or fed-batches, where the external glucose is kept low, a fully respiratory catabolism is observed. LÄS MER
