    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : .... READ MORE

  4. 2. Characterization of RNA polymerase II subunit Rpb7 in silencing and transcription

    Author : Ingela Djupedal; Karl Ekwall; Anthony Wright; Olivier Voinnet; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The DNA in eukaryotes is arranged in fibres of chromatin. The chromatin may be more or less compacted and the degree of condensation of the chromatin affects the accessibility of the DNA. The accessibility of the DNA, in turn, affects transcription and gene regulation. READ MORE

  5. 3. Genome wide analysis of the Ssn6-Tup11/Tup12 co-repressor complex in the fission yeast Schizosaccharomyces pombe

    Author : Fredrik Fagerström-Billai; Anthony Ph Wright; Karl Ekwall; Hans Ronne; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this study, we have investigated the fission yeast Ssn6-Tup11 /Tup 12 transcriptional corepressor which is involved in regulation of many genes important for a wide variety of processes. In contrast to the well characterised budding yeast Tup1 protein there are two paralogous proteins present in fission yeast, namely Tup11 and Tup12. READ MORE

  6. 4. Studies of Functional Interactions within Yeast Mediator and a Proposed Novel Mechanism for Regulation of Gene Expression

    Author : Magnus Hallberg; Stefan Björklund; Karl Ekwall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Mediator; Transcriptional regulation; Srb10; Cdk8; Med2; Srb7; Med21; RNA pol II; Biokemi; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Abstract : The yeast Mediator complex is required for transcriptional regulation both in vivo and in vitro and the identification of similar complexes from metazoans indicates that its function is conserved through evolution. Mediator subunit composition and structure is well characterized both by biochemical, genetic and biophysical methods. READ MORE

  7. 5. The Functional Significance and Chromatin Organisation of the Imprinting Control Regions of the H19 and Kcnq1 Genes

    Author : Meena Kanduri; Rolf Ohlsson; Karl Ekwall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; DNA methylation; Imprinting control region; Chromatin; Insulator; Nucleosome positioning; Genetik; Genetics; Genetik;

    Abstract : Genomic imprinting is a phenomenon through which a subset of genes are epigenetically marked during gemtogenisis. This mark is maintained in the soma to often manifest parent of origin-specific monoalleleic expresson patterns. READ MORE
