1. 1. The Adenovirus L4-33K Protein : A Key Regulator of Virus-specific Alternative Splicing

   Författare :Heidi Törmänen Persson; Göran Akusjärvi; Stefan Schwartz; Marie Öhman; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L4-33K; adenovirus; splicing; phosphorylation; localization; replication centers; L4-22K; MLTU; DNA-PK; DNA-dependent protein kinase; PKA; cAMP-dependent protein kinase; transcription sites; SR protein; Medical Virology; Medicinsk virologi;

   Sammanfattning : Adenoviruses have been extensively studied in the field of gene regulation, since their genes are subjected to a tightly controlled temporal expression during the virus lifetime. The early-to-late shift in adenoviral gene expression distinguishes two completely different programs in gene expression. LÄS MER

3. 2. 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

4. 3. Functional Characterization of the Cellular Protein p32 : A Protein Regulating Adenovirus Transcription and Splicing Through Targeting of Phosphorylation

   Författare :Christina Öhrmalm; Göran Akusjärvi; Neus Visa; Uppsala universitet; []
   Nyckelord :Cell and molecular biology; Adenovirus; p32; ASF SF2; E4-ORF4; Splicing; Transcription; CTD; RNA Pol II; Cell- och molekylärbiologi;

   Sammanfattning : Cellular processes involved in the conversion of the genetic information from DNA into a protein are often regulated by reversible phosphorylation reactions. By modulating the phosphorylated status of key proteins their activity can either be enhanced or repressed. LÄS MER

5. 4. Functional Characterization of the Evolutionarily Conserved Adenoviral Proteins L4-22K and L4-33K

   Författare :Sara Östberg; Göran Akusjärvi; Stefan Schwartz; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; L4-22K; L4-33K; RNA; splicing; adenovirus; nuclear localization; replication; transcription; evolution; SR protein; MLP; promoter; E1A; serotypes;

   Sammanfattning : Regulation of adenoviral gene expression is a complex process directed by viral proteins controlling a multitude of different activities at distinct phases of the virus life cycle. This thesis discusses adenoviral regulation of transcription and splicing by two proteins expressed at the late phase: L4-22K and L4-33K. LÄS MER

7. 5. Regulation of adenovirus alternative pre-mRNA splicing : Functional characterization of exonic and intronic splicing enhancer elements

   Författare :Bai-Gong Yue; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; adenovirus; pre-mRNA splicing; splicing enhancer; MLTU; L1; SR protein; ASF SF2; E. coli; phosphorylation; dephosphorylation; Biokemi; Biochemistry; Biokemi; mikrobiologi; Microbiology;

   Sammanfattning : Pre-mRNA splicing and alternative pre-mRNA splicing are key regulatory steps controlling geneexpression in higher eukaryotes. The work in this thesis was focused on a characterization of thesignificance of exonic and intronic splicing enhancer elements for pre-mRNA splicing. LÄS MER
