  2. 6. Solvation properties of proteins in membranes

    Author : Anna CV Johansson; Erik Lindahl; Mounir Tarek; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; lipid bilayer; free energy; solvation; insertion; molecular dynamics simulations; protein mass fraction; Theoretical chemistry; Teoretisk kemi; Biochemistry; biokemi;

    Abstract : Knowledge about the insertion and stabilization of membrane proteins is a key step towards understanding their function and enabling membrane protein design. Transmembrane helices are normally quite hydrophobic to insert efficiently, but there are many exceptions with unfavorable polar or titratable residues. READ MORE

  4. 7. Antibody Evolution and Repertoire Development

    Author : Johan Lantto; Institutionen för immunteknologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; serology; transplantation; Immunologi; serologi; virus neutralization; trinucleotide repeat; insertion; immunoglobulin variable genes; human cytomegalovirus; glycoprotein B; deletion; antibody; antibody repertoire;

    Abstract : Antibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer.

  5. 8. Variation in length of proteins by repeats and disorder regions

    Author : Rauan Sagit; Arne Elofsson; Andrey Kajava; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein length; repeats; domain repeats; protein evolution; duplication; tandem duplication; intrinsic disorder; intrinsically disordered; variation in length; insertion; deletion; recombination; expansion; contraction; Biochemistry; biokemi;

    Abstract : Protein-coding genes evolve together with their genome and acquire changes, some of which affect the length of their protein products. This explains why equivalent proteins from different species can exhibit length differences. READ MORE

  6. 9. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Author : Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Abstract : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. READ MORE

  7. 10. Effects and Dynamics of Insertion Sequences in the Evolution of Cyanobacteria

    Author : Carl Theoden Vigil Stenman; Birgitta Bergman; Andersson Siv; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cyanobacteria; Insertion Sequences; Evolution; Plant Physiology; växtfysiologi;

    Abstract : Cyanobacteria are globally widespread and ecologically highly significant photoautotrophic microorganisms, with diverse geno- and phenotypic characters unprecedented among prokaryotes. This phylum embraces representatives with an exclusive adaptability in highly specialized environments, from oligotrophic ocean waters to the interior of cells in symbiotic plants, the most extreme being the chloroplasts.
