  2. 1. Protein Tyrosine Phosphatases as Regulators of Receptor Ryrosine Kinases

    Author : Camilla Persson; Arne Östman; Niels Peter Moller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; protein tyrosine phosphatase; tyrosine kinase; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Tyrosine phosphorylation is a crucial mechanism in cellular signaling and regulates proliferation, differentiation, migration and adhesion. The phosphorylation reaction is reversible and is governed by two families of enzymes: protein tyrosine kinases and protein tyrosine phosphatases (PTPs). READ MORE

  4. 2. Ubiquitination and Receptor Endocytosis

    Author : Kaisa Haglund; Carl-Henrik Heldin; Ivan Dikic; Harald Stenmark; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Ubiquitination; receptor tyrosine kinase; endocytosis; Cbl; CIN85; EGFR; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Protein ubiquitination is an evolutionary conserved mechanism that controls a wide variety of cellular functions. Polyubiquitinated proteins are generally degraded in the proteasome, whereas monoubiquitination controls various other cellular processes, including endocytosis and endosomal sorting. READ MORE

  5. 3. The Tyrosine Kinase GTK : Signal Transduction and Biological Function

    Author : Cecilia Annerén; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinases; GTK; SHB; proliferation; survival; differentiation; β cells; pancreatectomy; cytokines; diabetes; PC12 cells; NGF; streptozotocin; focal adhesion kinase; RAP1; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

    Abstract : Originally studying the molecular mechanisms for the insulin-like effects of growth hormone (GH), lipogenesis and antilipolysis, in isolated rat adipocytes we found that the GH receptor (GHR) was tyrosine phosphorylated in response to GH in cells that were responsive to these effects. Then, as Janus kinase 2 (JAK2) was described as a GH-stimulated and GHR-associated tyrosine kinase, we found that JAK2 was tyrosine phosphorylated in response to GH in responsive cells. READ MORE
