  1. 1. Antibody Evolution and Repertoire Development

    Författare :Johan Lantto; Institutionen för immunteknologi; []
    Nyckelord :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;

    Sammanfattning : 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.

  3. 2. Variation in length of proteins by repeats and disorder regions

    Författare :Rauan Sagit; Arne Elofsson; Andrey Kajava; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

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

    Sammanfattning : 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. LÄS MER

  5. 4. Mine the Gaps : Evolution of Eukaryotic Protein Indels and their Application for Testing Deep Phylogeny

    Författare :Pravech Ajawatanawong; Sandra Baldauf; James McInerney; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; indel; insertion deletion; protein evolution; bioinformatics; non-bilateria; eukaryotes; phylogeny; Biology with specialization in Systematics; Biologi med inriktning mot systematik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : Insertions/deletions (indels) are potentially powerful evolutionary markers, but little is known about their evolution and few tools exist to effectively study them. To address this, I developed SeqFIRE, a tool for automated identification and extraction of indels from protein multiple sequence alignments. LÄS MER

  7. 5. Identification and characterisation of SMIM1 variants determining the Vel blood group

    Författare :Mikael Kronborg Christophersen; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Blood groups; Vel blood group system; genetic variation; transcriptional regulation;

    Sammanfattning : The Vel blood group antigen is present on red blood cells from all humans except rare Vel-negative individuals, who can form antibodies to Vel in response to transfusion or pregnancy. It was first described in 1952 as a high incidence antigen, while the molecular background was recently discovered to be a 17-bp deletion in Small Integral Membrane Protein 1, that causes a frame-shift mutation and abolishes SMIM1 expression, thus creating a Vel-negative phenotype.
