  1. 1. PARN – The Tail End : Function and mechanisms of specificity and processivity

    Författare :Mikael Nissbeck; Anders Virtanen; Renée Schroeder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poly A specific ribonuclease; Adenosine; Specificity; Processivty; Telomere biology disorders; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Poly(A)-specific ribonuclease (PARN) is an exoribonuclease that is processive, poly(A) specific and cap-binding. PARN deadenylates the poly(A) tails present on a subset of mRNAs and non-coding RNAs, including among others certain snoRNAs, miRNAs and precursor rRNAs. LÄS MER

  3. 2. Group I Introns and Homing Endonucleases in T-even-like Bacteriophages

    Författare :Linus Sandegren; Britt-Marie Sjöberg; Renée Schroeder; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage; Self-splicing introns; Homing endonucleases; Molecular biology; Molekylärbiologi;

    Sammanfattning : Homing endonucleases are rare-cutting enzymes that cleave DNA at a site near their own location, preferentially in alleles lacking the homing endonuclease gene (HEG). By cleaving HEG-less alleles the homing endonuclease can mediate the transfer of its own gene to the cleaved site via a process called homing, involving double strand break repair. LÄS MER

  4. 3. Small RNA-mediated Regulation of Gene Expression in Escherichia coli

    Författare :Cecilia Unoson; E. Gerhart. H Wagner; Renée Schroeder; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small RNA; non-coding RNA; antisense; translational control; ribosome standby; toxin-antitoxin; IstR; TisB; tisAB; MicF; Lrp; Microbiology; Mikrobiologi; Cell and molecular biology; Cell- och molekylärbiologi; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Sammanfattning : Non-coding RNAs are highly abundant regulators of gene expression in all kingdoms of life that often play important roles in vital cellular functions. In bacteria, small regulatory RNAs (sRNAs) usually act post-transcriptionally by regulating mRNAs through base pairing within ribosome binding sites (RBS), thereby inhibiting translation initiation.
