VEGFR-3 mediates lymphangiogenesis in response to VEGF-C and VEGF-D. [2] An example of a vital signal transduction pathway involves the tyrosine kinase receptor, c-met, which is required for the survival and proliferation of migrating myoblasts during myogenesis.
PI-3K initiates a positive feedback loop in which PtdIns(3,4,5), (B) The multiple domains of phospholipase C-γ (PLCγ) cooperate to integrate multiple signals at the plasma membrane.
For example, a map of the signaling network influenced by the EGFR node (.
These adaptor proteins link RTK activation to downstream signal transduction pathways, such as the MAP kinase signalling cascade. Differential regulation of EGF receptor internalization and degradation by multiubiquitination within the kinase domain. (A) A subset of intracellular signaling components influenced by epidermal growth factor receptor (EGFR) activation are intertwined in a complex network. FGFR family members are also mutated in a variety of cancers.
Structure of macrophage colony stimulating factor bound to FMS: diverse signaling assemblies of class III receptor tyrosine kinases. COSMIC (the Catalogue of Somatic Mutations in Cancer): a resource to investigate acquired mutations in human cancer. Targeting PI3K signalling in cancer: opportunities, challenges and limitations. Neither is it clear which ErbB receptors are activated by each of the several ErbB ligands (and to what extent), how ErbB receptors heterodimerize (and with what stoichiometry), or how rapidly different activated ErbB receptor complexes are internalized and disabled. [9] The phosphorylation of specific tyrosine residues within the activated receptor creates binding sites for Src homology 2 (SH2) domain- and phosphotyrosine binding (PTB) domain-containing proteins. Structural interactions of fibroblast growth factor receptor with its ligands. Cellular signaling by fibroblast growth factor receptors. Human receptor tyrosine kinases (RTKs) contain 20 subfamilies, shown here schematically with the family members listed beneath each receptor. Although EphA10 is involved in the malignancy of some types of cancer, its role as an oncogene has not been extensively studied. The transcriptional response to Raf activation is almost completely dependent on Mitogen-activated Protein Kinase Kinase activity and shows a major autocrine component. Not just a sink: endosomes in control of signal transduction. Activating mutations in the epidermal growth factor receptor underlying responsiveness of non-small-cell lung cancer to gefitinib. Neurotrophic factor receptor RET: structure, cell biology, and inherited diseases.
