  1. 1. Protein Misfolding in Human Diseases

    Författare :Karin Almstedt; Per Hammarström; Daniel Otzen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Misfolding; carbonic anhydrase; prion protein; protein stability; Biochemistry; Biokemi;

    Sammanfattning : There are several diseases well known that are due to aberrant protein folding. These types of diseases can be divided into three main categories:Loss-of-function diseasesGain-of-toxic-function diseasesInfectious misfolding diseases Most loss-of-function diseases are caused by aberrant folding of important proteins.

  2. 2. Protein folding without loops and charges

    Författare :Martin Kurnik; Mikael Oliveberg; Kevin W. Plaxco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein folding; folding cooperativity; protein aggregation; protein charges; protein engineering; Biochemistry; biokemi;

    Sammanfattning : Going down the folding funnel, proteins may sample a wide variety of conformations, some being outright detrimental to the organism. Yet, the vast majority of polypeptide molecules avoid such pitfalls. Not only do they reach the native minimum of the energy landscape; they do so via blazingly fast, biased, routes. LÄS MER

  3. 3. Fluorescent Probes and Protein Misfolding: Methods and Applications

    Författare :Irem Nasir; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Protein misfolding; fluorophores; filter-trap; site-specific fluorophore labeling; amyloid-beta; microscopic rate constants; solvatochromic probes; alpha-synuclein; lipid vesicles; nanoparticles; protein adsorption;

    Sammanfattning : Protein misfolding is a frequently occurring event in living cells and without the quality control, the consequences are disasterous. In this thesis, we studied protein misfolding in vitro by employing a variety of fluorophores, to either detect the highly ordered aggregates of intrinsically disordered proteins/peptides or slight misfolding of a natively folded protein.

  4. 4. Zinc in folding and misfolding of SOD1 : Implications for ALS

    Författare :Lina Leinartaité; Mikael Oliveberg; Bengt-Harald Jonsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein stability; protein misfolding; local unfolding; metal binding; energy landscape; protein disease; amyotrophic lateral sclerosis; Biochemistry; biokemi;

    Sammanfattning : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease causing degeneration of upper and lower motor neurons. Most ALS cases are sporadic; only 6% are associated with mutations in Cu, Zn superoxide dismutase (SOD1). LÄS MER

  5. 5. Protein complexes : assembly, structure and function

    Författare :Kristina Wilhelm; Ludmilla Ludmilla Morozova-Roche; Catharina Svanborg; Umeå universitet; []
    Nyckelord :HAMLET; ELOA; lysozyme; amyloid; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning :  Most proteins must fold into their native conformations to fulfil their biological functions. Failure of proteins to fold leads to cell pathology and a broad range of human diseases referred to as protein misfolding disease, e.g., Alzheimer’s disease, Parkinson’s disease, and type II diabetes.
