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. 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. Regulation of RNA polymerase I and RNA polymerase III transcription by the chromatin remodelling complex B-WICH

   Författare :Fatemeh Sadeghifar; Ann-Kristin Östlund Farrants; Magdalena Boguta; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; B-WICH; Chromatin remodelling; ribosomal genes; transcription; Cell Biology; cellbiologi;

   Sammanfattning : Ribosomal biogenesis is an important process which determines the rate of cell growth and is involved in cell response to proliferation, differentiation, cellular nutritional state and stress. The chromatin remodelling complex B-WICH composed of WSTF, SNF2h and NM1 is involved in transcription by the RNA pol I and RNA pol III. LÄS MER

5. 4. Transcriptional regulation of ribosomal RNA gene : actin, myosin and beyond

   Författare :Aishe Angeletti Sarshad; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : In the eukaryotic cell nucleus, actin and nuclear myosin 1c (NM1) are key regulators of RNA polymerase I (Pol I) transcription and function across the entire ribosomal RNA biogenesis pathway. At the gene level, actin interacts with Pol I and together with NM1 they have been suggested to facilitate assembly of Pol I at the gene promoter. LÄS MER

7. 5. Actin and myosin in transcription and chromatin regulation

   Författare :Bader Almuzzaini; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : In mammalian cells, actin and myosin have emerged as regulators of nuclear structure and function, involved in chromatin remodeling and histone modifications, and in different phases of gene transcription. Actin and myosin have also been shown to be incorporated into nascent ribonucleoprotein complexes. LÄS MER
