  1. 1. Molecular mechanisms for transcription in mammalian mitochondria

    Författare :Martina Gaspari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :mitochondria; oxidative phosphorylation; mtDNA; transcription; TFAM; TFB1M TFB2M; POLRMT; promoter recognition; CSB II;

    Sammanfattning : The circular double stranded mitochondrial genome (mtDNA), which is about 16,600 bp in humans and 16,300 bp in mice, encodes 13 of the -90 different proteins present in the respiratory chain of mammalian mitochondria. The remaining components of the respiratory chain are encoded by nuclear genes and imported into the mitochondrial network. LÄS MER

  3. 2. Chromatin remodelling in Pol I and III transcription

    Författare :Erica Cavellán; Ann-Kristin Östlund Farrants; Gernot Längst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi;

    Sammanfattning : Compaction of chromosomes in the eukaryotic cell is due to interactions between DNA and proteins and interactions between proteins. These two types of interaction form a dynamic structure, known as "chromatin". The condensation of chromatin must be carefully regulated, since the structure is an obstacle for factors that need access to the DNA. LÄS MER

  4. 3. 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.
