  2. 1. Eukaryotic Ribosome Biogenesis : Focus on the function of the assembly factor Mrd1p

    Author : Åsa Segerstolpe; Lars Wieslander; Susan Gerbi; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Ribosome biogenesis; nucleolus; pre-rRNA processing; RNA-binding proteins; Mrd1; Molecular Biology; molekylärbiologi;

    Abstract : The ribosome, the protein factory of the cell, is essential for all life forms. The ribosome is a large RNA-protein machine. It is built in a complex, multi-step process that involves a large number of accessory trans-acting factors and the synthesis consumes a considerable part of the cellular energy. READ MORE

  4. 2. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

    Author : Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

    Abstract : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. READ MORE

  5. 3. Nucleolar Ribosome Assembly

    Author : Fredrik Lackmann; Lars Wieslander; Denis Lafontaine; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ribosome biogenesis; RNA; Nucleolus; Molecular Biology; molekylärbiologi;

    Abstract : Ribosomes are macromolecular machines that are responsible for production of every protein in a living cell. Yet we do not know the details about how these machines are formed. The ribosome consists of four RNA strands and roughly 80 proteins that associate with each other in the nucleolus and form pre-ribosomal complexes. READ MORE

  6. 4. Ribosome biogenesis during skeletal muscle hypertrophy

    Author : Ferdinand von Walden; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Muscle adaptation to chronic resistance exercise (RE) is the result of a cumulative effect on gene expression and protein content. Following a bout of RE, muscle protein synthesis increases and, if followed by consecutive bouts (training), protein accretion and muscle hypertrophy develops. READ MORE

  7. 5. Ribosomal RNA Modification Enzymes : Structural and functional studies of two methyltransferases for 23S rRNA modification in Escherichia coli

    Author : Avinash S. Punekar; Maria Selmer; Martino Bolognesi; Uppsala universitet; []

    Abstract : Escherichia coli ribosomal RNA (rRNA) is post-transcriptionally modified by site-specific enzymes. The role of most modifications is not known and little is known about how these enzymes recognize their target substrates. READ MORE
