  1. 6. Viral Control of SR Protein Activity

    Författare :Camilla Estmer Nilsson; Neus Visa; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; ASF SF2; dephosphorylation; E4-ORF4; L1; MLTU; PP2A; splicing; SR proteins; vaccinia virus; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Viruses modulate biosynthetic machineries of the host cell for a rapid and efficient virus replication. One important way of modulating protein activity in eukaryotic cells is by reversible phosphorylation. In this thesis we have studied adenovirus and vaccinia virus, two DNA viruses with different replication stategies. LÄS MER

  3. 7. Viral Strategies to Regulate Transcription and Pre-mRNA Splicing

    Författare :Shaoan Fan; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Adenovirus E1B-55kDa; E4-ORF4; E4-ORF6 proteins; L1 mRNA; Polyoma virus small T antigen; regulation; transcription; splicing; PP2A; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : A typical DNA virus encodes for a few key regulatory proteins that modify the host cell biosynthetic machinery to achieve a selective viral gene statement. One such example is illustrated by the adenovirus E4-ORF4 protein, which form an enzymatically active complex with the serine and threonine-specific protein phosphatase 2A (PP2A). LÄS MER

  4. 8. Protein interactions involved in viral replication characterized by T7 phage display

    Författare :Hamid Houshmand; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; protein-protein interaktion; fagdisplayteknik; HCV; polyomavirus; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Protein interactions are essential for many cellular processes. By utilizing protein-protein interactions, viruses can infect their host cells and replicate. Phage display can be used for identification and characterization of protein-protein interactions. LÄS MER

  5. 9. Activity of tumor-antigens in polyomavirus replication

    Författare :Hongyun Li; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Tumor-Antigens; DNA Replication; Cell-cycle; Phosphorylation; J-domain; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : Polyomavirus replication needs an active cell environment, and the viral DNA replication is cell cycle regulated. Tumor antigens (T-antigens) of mouse polyomavirus, especially large T-antigen, are necessary for the replication. LÄS MER

  7. 10. Adenovirus vector systems permitting regulated protein expression and their use for in vivo splicing studies

    Författare :Magnus Molin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Adenovirus; vector; inducible; gene expression; ASF SF2; splicing; Biokemi; Biochemistry; Biokemi; Medical Virology; medicinsk virologi;

    Sammanfattning : We have constructed two adenovirus-based gene expression vector systems permitting regulated protein expression. They are based on the tetracycline-regulated Tet-ON- and the progesterone antagonist RU 486-regulated gene expression systems, which were rescued into E1-deficient adenovirus vectors. LÄS MER
