  1. 6. Regulatory mechanisms of amino acid-induced signaling in Saccharomyces cerevisiae

    Författare :Deike J. Omnus; Per O. Ljungdahl; Claudio De Virgilio; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Signal transduction; regulatory mechanisms; nutrient sensing; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : This thesis describes studies aimed at elucidating the molecular mechanisms that regulate the SPS (Ssy1-Ptr3-Ssy5) signal transduction pathway in the yeast Saccharomyces cerevisiae. This pathway is induced by extracellular amino acids and facilitates their uptake. LÄS MER

  3. 7. In vivo analysis of amino acid permease folding in yeast

    Författare :Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; endoprotease; subcellular fractionation; membrane-localized chaperone; amino acid permease; endoplasmic reticulum; membrane protein folding; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Sammanfattning : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. LÄS MER

  5. 9. Chromatin remodelling of ribosomal genes - be bewitched by B-WICH

    Författare :Anna Vintermist; Ann-Kristin Östlund Farrants; Ross D. Hannan; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatin remodelling; ribosomal genes; rDNA; transcription; RNA polymerase I transcription; RNA polymerase III transcription; Cell Biology; cellbiologi;

    Sammanfattning : Transcription of the ribosomal genes accounts for the majority of transcription in the cell due to the constant high demand for ribosomes. The number of proteins synthesized correlates with an effective ribosomal biogenesis, which is regulated by cell growth and proliferation. LÄS MER

  7. 10. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Författare :Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. LÄS MER
