  1. 1. Multifaceted RNA-mediated regulatory mechanisms in Streptococcus pyogenes

    Författare :Anaïs Le Rhun; Emmanuelle Charpentier; Franz Narberhaus; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Streptococcus pyogenes; small RNAs; CRISPR; Cas9; tracrRNA; RNases; gene expression; RNA sequencing; Infectious Diseases; infektionssjukdomar; mikrobiologi; Microbiology;

    Sammanfattning : Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. LÄS MER

  3. 2. Post-transcriptional regulation by RNases in Streptococcus pyogenes

    Författare :Anne-Laure Lécrivain; Emmanuelle Charpentier; Bernt Eric Uhlin; Tracy Nissan; Ciarán Condon; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Post-transcriptional regulation; mRNA decay; RNA sequencing; RNase Y; RNase III; YhaM; PNPase; RNase R; RNase J1; Streptococcus pyogenes.; molekylärbiologi; Molecular Biology;

    Sammanfattning : Ribonucleases (RNases) are proteins that adjust cellular RNA levels by processing RNA transcripts, leading to their stabilization or degradation. RNases are grouped based on their ability to cleave the transcript internally (endoRNases) or degrade the transcript starting from the ends (exoRNases). LÄS MER

  4. 3. Computational identification of non-coding RNAs

    Författare :Paul Piccinelli; Göteborgs universitet; []
    Nyckelord :RNase P; RNase MRP; IRE; non-coding RNA; secondary structure;

    Sammanfattning : A large amount of genomic information is now becoming available. Suitable bioinformatic tools to organize and analyze this vast amount of information are therefore important. In the case of protein genes, the majority of these may be correctly identified using standard search methods that are based on sequence alignment. LÄS MER

  5. 4. Evolution of protein and non-coding RNA genes studied with comparative genomics

    Författare :Marcela Davila Lopez; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bioinformatics; evolution; non-coding RNA; gene prediction; gene order; bidirectional promoter; homologue prediction; secondary structure; RNAse P; RNase MRP;

    Sammanfattning : The identification of protein and non-coding RNA (ncRNA) genes is one important step in the analysis of a genome. This thesis focuses on the identification and analysis of proteins and ncRNAs homologues by exploiting a variety of computational methods in order to reach conclusions as to their structure, function, evolution and regulation.
