  1. 1. Statistical models of TF/DNA interaction

    Author : Aymeric Fouquier d'Herouel; Erik Aurell; Otto Berg; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; gene expression; regulation; transcription factor; binding motif; matrix representations; gibbs sampling; binding affinity; non-specific binding; Biological physics; Biologisk fysik;

    Abstract : Gene expression is regulated in response to metabolic necessities and environmental changes throughout the life of a cell. A major part of this regulation is governed at the level of transcription, deciding whether messengers to specific genes are produced or not. READ MORE

  2. 2. DNA Interaction Dynamics of Ruthenium(II) Complexes

    Author : Fredrik Westerlund; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; fluorescence; ruthenium; polarized spectroscopy; threading; sequence selectivity; photophysics; binding kinetics; DNA; intercalation;

    Abstract : DNA-binding of small synthetic ligands is of great importance in a number of different applications, from medicine to molecular biology. This thesis focuses on interactions between DNA and ruthenium(II) complexes, in particular the dimers [µ-bidppz(L)4Ru2]4+ (L=1,10-phenanthroline (P) or L=2,2-bipyridine (B)). READ MORE

  3. 3. Combinatorial Methodology. Screening for affinity specific ligands to biological and artificial receptors

    Author : Margareta Krook; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; peptide library; combinatorial; screening; phage display; affinity; DNA-interaction; chymotrypsin; peptide inhibitor; antibody; IgG; Fc; molecular imprinting; steroid; receptor; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik;

    Abstract : Combinatorial screening methodology has been employed to select new affinity specific ligands to bilogical and artificial receptors. The screening methodology, in particular screening of combinatorial phage display peptide libraries against target molecules differing in function and shape, is focused upon. READ MORE

  4. 4. Functional and structural properties of eukaryotic DNA polymerase epsilon

    Author : Olga Chilkova; Erik Johansson; Per Elias; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; eukaryotic DNA replication; DNA polymerase epsilon; protein-DNA interaction; Biochemistry; Biokemi;

    Abstract : In eukaryotes there are three DNA polymerases which are essential for the replication of chromosomal DNA: DNA polymerase alpha (Pol alpha), DNA polymerase delta (Pol delta) and DNA polymerase epsilon (Pol epsilon). In vitro studies of viral DNA replication showed that Pol alpha and Pol delta are sufficient for DNA replication on both leading and lagging DNA strands, thus leaving the function of Pol epsilon unknown.

  5. 5. Visualizing Interacting Biomolecules In Situ

    Author : Irene Weibrecht; Ola Söderberg; Ulf Landegren; Banafshe Larijani; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proximity ligation; in situ PLA; padlock probe; rolling circle amplification; flow cytometry; in situ; single cell; single molecule; protein interaction; protein-DNA interaction; posttranslational modification; Molecular medicine; Molekylär medicin; Molekylär medicin; Molecular Medicine;

    Abstract : Intra- and intercellular information is communicated by posttranslational modifications (PTMs) and protein-protein interactions, transducing information over cell membranes and to the nucleus. A cells capability to respond to stimuli by several highly complex and dynamic signaling networks provides the basis for rapid responses and is fundamental for the cellular collaborations required in a multicellular organism.
