  1. 1. Exploring the Interplay of Lipids and Membrane Proteins

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Candan Ariöz; Stockholms universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation;

    Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER

  2. 2. The Membrane Proteome Evolution, Characteristics and Classification

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Markus Sällman Almén; Uppsala universitet.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Membrane proteome; molecular evolution; GPCRs; Dispanins; IFITM; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Membrane proteins are found in all kingdoms of life and are essential for cellular interactions with the environment. Although a large research effort have been put into this group many membrane proteins remains uncharacterized, both in terms of function and evolutionary history. LÄS MER

  3. 3. Sperm Membrane Channels, Receptors and Kinematics Using boar spermatozoa for drug toxicity screening

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Alejandro Vicente Carrillo; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Plasma membrane; membrane channels; membrane receptors; kinematics; 3Rprinciples; spermatozoa; boar.;

    Sammanfattning : Internal fertilization usually implies that a spermatozoon, with intact attributes for zygote formation, passes all hurdles during its transport through the female genitalia and reaches the oocyte. During this journey, millions to billions of other spermatozoa perish. LÄS MER

  4. 4. Interaction of Calcium Ions with Lipid Membranes

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Baharan Ali Doosti; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phospholipid bilayer membrane; membrane dynamics; micromanipulation; calcium ions; cell migration.; membrane nanotube; membrane tubular protrusions; calcium ion concentration gradient; membrane bending; giant unilamellar vesicle;

    Sammanfattning : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

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

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Gustav Nordlund; Stockholms universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lipids; membrane proteins; method development; respiration; reconstitution; supported membranes; SNAREs; liposome fusion; lipid-protein interactions; biokemi; Biochemistry;

    Sammanfattning : 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.
