  2. 1. Characterization of the DNA-Binding Properties of the Cyanobacterial Transcription Factor NtcA

    Author : Susanne Wisén; Bengt Mannervik; Enrique Flores; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; NtcA; transcription regulation; cyanobacteria; redox regulation; DNA binding; nitrogen fixation; Anabaena PCC 7120; Biokemi; Biochemistry; Biokemi;

    Abstract : Nitrogen is an essential building block of proteins and nucleic acids and, therefore, crucial for the biosphere. Nearly 79 % of the air consists of nitrogen, but in the form of nitrogen gas (N2), which cannot be utilized by most organisms. READ MORE

  4. 2. DNA and protein interactions of mouse polyomavirus large T antigen

    Author : Ola Rönn; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; T-antigen; DNA-binding; biosensor; enhancer; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Abstract : Polyomaviruses require dividing cells to multiply. The regulatory genes express proteins, theT-antigens, necessary for this to occur. Large T-antigen (LT), is a phosphoprotein withmultiple intrinsic activities, e.g. READ MORE

  5. 3. Regulation of TGF-β Signaling by Post-Translational Modifications

    Author : Peter Lönn; Aristidis Moustakas; Carl-Henrik Heldin; Petra Knaus; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TGF-β; Smad; PARP-1; PARG; ALK5; SIK; signal transduction; transcription; post-translational modification; phosphorylation; ubiquitin; ADP-ribosylation; DNA-binding; receptor degradation; Cell and molecular biology; Cell- och molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Abstract : Transforming growth factor-β (TGF-β) signaling is initiated when the ligand binds to type II and type I serine/threonine kinase receptors at the cell surface. Activated TGF-β type I receptors phosphorylate R-Smads which relocate, together with co-Smads, to the cell nucleus and regulate transcription. READ MORE

  7. 5. Functional Studies of Telomere-Binding Proteins in Saccharomyces castellii

    Author : Jenny Rhodin; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rap1; DNA-binding domain; telomere evolution; Cdc13; telomerase; single-stranded overhang; telomere; yeast; Naumovia castellii; Saccharomyces castellii;

    Abstract : Telomeres are the ends of linear eukaryotic chromosomes. The telomeres are essential for solving the end replication problem and they stabilize the genome by protection from degradation. The telomeres also protect the chromosomal ends from by being recognized as DNA breaks by the repair machinery, which could lead to end-to-end fusions. READ MORE
