  1. 1. Chromatin Remodeling by BRG1 and SNF2H : Biochemistry and Function

    Författare :Patrik Asp; Ann-Kristin Östlund Farrants; Anthony Imbalzano; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatin; chromatin remodeling; SWI SNF; ISWI; BRG1; SNF2H; Prp8; RNA; transcription; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Chromatin is a highly dynamic, regulatory component in the process of transcription, repair, recombination and replication. The BRG1 and SNF2H proteins are ATP-dependent chromatin remodeling proteins that modulate chromatin structure to regulate DNA accessibility for DNA-binding proteins involved in these processes.

  3. 2. Molecular mechanisms underlying the activation of ALC1 nucleosome remodeling

    Författare :Luka Bacic; Sebastian Deindl; Stefan D. Knight; Lari Lehtiö; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ALC1; CHD1L; nucleosome; ADP-ribosylation; chromatin; remodeling; PARP1; HPF1; DNA damage; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Packaging DNA into chromatin represses essential DNA-based processes, such as transcription, DNA replication, and repair. To change the accessibility of DNA, cells have evolved a set of enzymes referred to as chromatin remodelers that act on the basic repeat unit of chromatin,  the nucleosome. LÄS MER

  4. 3. Chromatin remodelers and their roles in chromatin organization

    Författare :Annelie Strålfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The DNA in the eukaryotic nucleus is organized into a complex DNA-protein structure called chromatin. The basic repeating unit of chromatin is the nucleosome, which consists of 147 bp of DNA wrapped around a histone protein octamer. LÄS MER

  5. 4. The CHD chromatin remodeling factors in schizosaccharomyces pombe

    Författare :Julian Walfridsson; Karl Ekwall; Pernilla Bjerling; Stefan Björklund; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Regulation of chromatin structure is essential in a wide variety of processes including transcriptional regulation, recombination, replication, chromosome segregation, development and differentiation. The enzymes that are central in regulating chromatin structure can be classified into two major groups. LÄS MER

  7. 5. Notch signaling : from receptor cleavage to chromatin remodeling

    Författare :Kia Strömberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One of the principal signaling mechanisms that control development of multicellular organisms is the Notch signaling pathway. The transmembrane Notch receptor, presented at the cell surface, interacts with ligand on neighbouring cells. LÄS MER
