  1. 1. Membrane-bound proteins : Characterization, evolution, and functional analysis

    Author : Misty M. Attwood; Helgi B. Schiöth; Arne Elofsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transmembrane protein; alpha-helical membrane protein; evolution membrane proteins; 3TM; 4TM; 5TM; trispanin; Bioinformatics; Bioinformatik;

    Abstract : Alpha-helical transmembrane proteins are important components of many essential cell processes including signal transduction, transport of molecules across membranes, protein and membrane trafficking, and structural and adhesion activities, amongst others. Their involvement in critical networks makes them the focus of interest in investigating disease pathways, as candidate drug targets, and in evolutionary analyses to identify homologous protein families and possible functional activities.

  2. 2. Membrane-mimetic systems : Novel methods and results from studies of respiratory enzymes

    Author : Gustav Nordlund; Peter Brzezinski; Joachim Heberle; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; Biochemistry; biokemi;

    Abstract : The processes localized to biological membranes are of great interest, both from a scientific and pharmaceutical point of view. Understanding aspects such as the detailed mechanism and regulation of these processes requires investigation of the structure and function of the membrane-bound proteins in which they take place.

  3. 3. One key to two doors : Dual targeting peptides and membrane mimetics

    Author : Weihua Ye; Lena Mäler; Göran Kalsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : Dual targeting peptides; protein import; mitochondria and chloroplasts; bicelles; galactolipids; NMR spectroscopy; Biophysics; biofysik;

    Abstract : A targeting peptide at the N-terminus of a precursor protein usually directs the protein synthesized in the cytosol to a specific organelle in the cell. Interestingly, some targeting peptides, so-called dual targeting peptides (dTPs) can target their protein to both mitochondria and chloroplasts. READ MORE

  4. 4. Cell-penetrating peptide targeting mitochondria : Design, synthesis, characterization, and biological effects

    Author : Carmine Pasquale Cerrato; Ülo Langel; Lena Mäler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cell-penetrating peptide; mitochondrial targeting; ROS reduction; mitochondrial membrane potential; antioxidant activity; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : More than twenty years after the discovery of the first cell-penetrating peptide (CPP), a large number of both naturally occurring as well as engineered CPPs have been discovered. Generally, CPPs are short polycationic sequences of less than 30 amino acids that are able to translocate different cargoes into cells. READ MORE

  5. 5. Membrane Protein Biogenesis in Escherichia coli : A proteomics approach

    Author : David Vikström; Jan-Willem de Gier; Eitan Bibi; Stockholms universitet; []
    Keywords : SRP; YidC; SecE; Membrane protein biogenesis; protein targeting; 2D BN SDS-PAGE; Biochemistry; biokemi;

    Abstract : In the bacterium Escherichia coli all proteins are synthesized in the cytoplasm. However, at least 25% of them then need to be exported to another cellular compartment where they exert their function. E. coli has several different targeting pathways to ensure the correct localization of its proteins. READ MORE
