  2. 1. PARN - A Tale of A de-Tailor : Functional importance of poly(A) degradation in developmental and telomere biology disorders

    Author : Sethu Madhava Rao Gunja; Anders Virtanen; Jonas von Hofsten; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PARN; Telomere biology disorders; snoRNAs; scaRNAs; TR TERC; Zebrafish; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Molekylär genetik; Molecular Genetics; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Poly(A)-specific ribonuclease (PARN) is a eukaryotic 3’-5’exoribonuclease that removes poly(A) tails of many coding and non-coding RNAs. In this thesis, we have studied the physiological role of PARN. READ MORE

  4. 2. Poly(A)-specific Ribonuclease (PARN) : Structural and Functional Studies of Poly(A) Recognition and Degradation

    Author : Niklas Henriksson; Anders Virtanen; Marvin Wickens; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Cell- och molekylärbiologi; Molecular Biotechnology; Molekylär bioteknik;

    Abstract : Regulation of mRNA degradation is a powerful way for the cell to regulate gene expression. A critical step in eukaryotic mRNA degradation is the removal of the poly(A) tail at the 3'-end of the mRNA. READ MORE

  5. 3. Allosteric Regulation of mRNA Metabolism : -Mechanisms of Cap-Dependent Regulation of Poly(A)-specific Ribonuclease (PARN)

    Author : Per Nilsson; Anders Virtanen; Megerditch Kiledjian; Uppsala universitet; []
    Keywords : Cell and molecular biology; mRNA degradation; deadenylation; cap; poly A ; PARN; allosteric regulation; Cell- och molekylärbiologi;

    Abstract : Degradation of mRNA is a highly regulated step important for proper gene expression. Degradation of eukaryotic mRNA is initiated by shortening of the 3’ end located poly(A) tail. Poly(A)-specific ribonuclease (PARN) is an oligomeric enzyme that degrades the poly(A) tail with high processivity. READ MORE

  6. 4. The Mimetic Mystery : A linguistic study of the genre of British and American detective fiction including a comparison with suspense fiction

    Author : Margit Bönnemark; Tuija Virtanen; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; English language; Engelska språket;

    Abstract : The present study is an analysis of the genre of detective fiction from a predominantly linguistic point of view.The main hypothesis is that the addresser's aims determine not only the content of a text but also its discursive and textual properties. READ MORE

  7. 5. A Dynamic and Adaptive Information Security Awareness (DAISA) Approach

    Author : Respickius Casmir; Louise Yngström; Teemupekka Virtanen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

    Abstract : Information systems fail not only because of problems with technology used and technical incompetence of professionals administering them but also because of lack of security awareness to the end users. In addition, various research results have revealed that security and reliability of IS/IT systems is a function of technology, processes and people. READ MORE
