  2. 1. Expression, regulation and fuction of small ubiquitin-related modifier-1. Interaction with nuclear proteins in vivo

    Author : Linus Ruijin Shao; Göteborgs universitet; []
    Keywords : SUMO-1; LH receptor; PR isoforms; caspase-3; DNA fragmentation; apoptosis; granulosa cells; HIF-1alpha; hypoxia; brain and heart;

    Abstract : The small ubiquitin-related modifier-1 (SUMO-1) is a 101-amino acid, ~12 kDa protein that is 18% identical to ubiquitin. Posttranslational covalent tagging of proteins with SUMO-1 (SUMOylation) serves many functions. For example, regulation of protein stability and modulation of transcriptional activation. READ MORE

  4. 2. Subcellular localization and signalling of Brutons tyrosine kinase (Btk)

    Author : Leonardo Vargas-Vallejo; Karolinska Institutet; Karolinska Institutet; []
    Keywords : B-cells; Brutons tyrosine kinase; X-linked agammaglobulinemia; pleckstrin homology domain; cytoskeleton; nucleocytoplasmic shuttling; caveolin-1; ubiquitin; SUMO-1.;

    Abstract : Brutons tyrosine kinase (Btk) is a non-receptor tyrosine kinase related to the Src family of kinases. Mutations in various parts of the gene have been shown to cause X-linked agammaglobulinemia (XLA), a primary immunodeficiency in humans, characterized by a defect in B-cell development. READ MORE

  5. 3. THE ANGIOGENIC RESPONSE IN HYPOXIC HEART. Experimental studies in mice

    Author : Fei Tian; Göteborgs universitet; []
    Keywords : hypoxia; angiogenesis; mice; endoglin; SUMO; PDI;

    Abstract : Coronary artery disease is the leading cause of death in the western world today. Although induction of angiogenesis would appear to be an ideal therapeutic strategy, clinical trials of proangiogenic factors have proved disappointing. READ MORE

  6. 4. From membrane to nucleus : new roles and functions of SUMOylated IGF-1R and EGFR

    Author : Sylvia Packham; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cell surface receptor tyrosine kinases (RTKs) role in cell signaling have been studied for decades and their role in cancer progression are undisputable. The insulin-like growth factor 1 receptor, IGF-1R, has been demonstrated to play a critical part in tumorigenesis; downregulation of the IGF-1R in tumor xenografts results in complete tumor regression.

  7. 5. Identification and functional characterization of Epstein-Barr virus-encoded deconjugases

    Author : Sebastian Hildebrand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The post-translational conjugation or deconjugation of proteins by ubiquitin (Ub) or ubiquitin-like molecules (UbLs: e.g. SUMO, NEDD8, ISG15) has emerged as a major regulatory mechanism of various cellular activities. READ MORE
