  2. 2. Elongation factor 2: A key component of the translation machinery in eukaryotes : Properties of yeast elongation factor 2 studied in vivo

    Author : Galyna Bartish; Odd Nygård; Suparna Sanyal; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Elongation factor 2; yeast; ribosome; phosphorylation; Switch I; site-directed mutagenesis; functional complementation; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : Synthesis of proteins is performed by the ribosome, a large ribonucleoprotein complex. Apart from the ribosome, numerous protein factors participate in this process. Elongation factor 2 (eEF2) is one of these factors. eEF2 is an essential protein with a mol. READ MORE

  3. 3. The ribosome, stringent factor and the bacterial stringent response

    Author : Rose-Marie Jenvert; Lovisa Holmberg Schiavone; Suparna Sanyal; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ribosome; stringent factor; stringent response; tRNA; ribosomal protein L11; pppGpp; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : The stringent response plays a significant role in the survival of bacteria during different environmental conditions. It is activated by the binding of stringent factor (SF) to stalled ribosomes that have an unacylated tRNA in the ribosomal A-site which leads to the synthesis of (p)ppGpp. READ MORE

  4. 4. The Actin Filament System : Its Involvement in Cell Migration and Neurotransmitter Release

    Author : Anna-Karin Johnsson; Roger Karlsson; Stéphane Gasman; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Actin; Profilin; Synaptotagmin; Cell biology; Cellbiologi; Cell Biology; cellbiologi;

    Abstract : The microfilament system consists of actin filaments as the major component and is regulated by a number of actin binding proteins. It is juxtaposed to the plasma membrane where it forms a dense cortical weave from where it pervades into the cell interior. READ MORE

  5. 5. Cell Behavior and the Role of Profilin

    Author : Yu Li; Roger Karlsson; Christophe Ampe; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell biology; Cellbiologi; cellbiologi; Cellbiology;

    Abstract : Profilin is a key regulator of the microfilament system. It binds to actin monomers in a 1:1 complex, forming the profilin:actin complex, which is the major precursor of actin for filament formation in vivo. The distribution of profilin has been studied in a variety of cells. It is present not only in the cytoplasm but also in the nucleus. READ MORE
