1. 11. Regulation of gene expression in fruit flies : how does it start, and will it be remembered?

   Författare :Aman Zare; Per Stenberg; Yuri B. Schwartz; Åsa Rasmuson-Lestander; Guillaume Filion; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; epigenetics; transcription; gene regulation; transcription maintenance; CBP; polymerase pausing; Polycomb group proteins; transgenerational inheritance of transcriptional response; gut microbiome; molekylärbiologi; Molecular Biology;

   Sammanfattning : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

3. 12. Studies of the chromatin form of yeast Mediator and the function of its tail module

   Författare :Miriam Nilsson; Stefan Björklund; Claes Gustafsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mediator complex; Transcriptional regulation; yeast; tail module; transcription; medicinsk biokemi; Medical Biochemistry; molekylärbiologi; Molecular Biology;

   Sammanfattning : Mediator is a large, multifunctional complex that is conserved in eukaryotes. It was first discovered in Saccharomyces cerevisiaeas required for transcriptional activators to function in a reconstituted in vitro system. Mediator is also important for stimulation of basal, unregulated transcription, and transcriptional repression. LÄS MER

4. 13. 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. 14. Calcium regulation and functions of basic Helix-Loop-Helix transcription factors

   Författare :Juha Saarikettu; Thomas Grundström; Dan Holmberg; Mikael Sigvardsson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; calcium; calmodulin; calretinin; transcription; bHLH; E-protein; E2-2; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : The members of the ubiquitously expressed E-protein subfamily of basic Helix-Loop-Helix (bHLH) transcription factors, E12/E47, SEF2-1 and HEB, have important roles as regulators of gene expression in various differentiation processes, including lymphocyte development and myogenesis. In myogenesis, E-proteins are proposed to function as obligate heterodimer partners for members of the MyoD family of muscle-specific bHLH transcription factors. LÄS MER

7. 15. ATPase dependent and independent roles of Brahma in transcription and pre-mRNA processing

   Författare :Simei Yu; Neus Visa; Ann-Kristin Östlund Farrants; Christian Muchardt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatin remodeling; transcription; alternative splicing; 3 -end processing; Molecular Biology; molekylärbiologi;

   Sammanfattning : SWI/SNF is a chromatin-remodeling complex and Brahma (BRM) is the ATPase subunit of SWI/SNF. BRM regulates transcription by remodeling the nucleosomes at promoter regions. BRM is also associated with RNA and affects pre-mRNA processing together with other SWI/SNF subunits. LÄS MER
