IP3 production in the hypersensitive response of lemon seedlings against Alternaria alternata involves active protein tyrosine kinases but not a G-protein.
IP3 increase and de novo synthesis of scoparone are produced in the hypersensitive response (HR) of lemon seedlings against the fungus Alternaria alternata. To elucidate whether a G-protein and/or a protein tyrosine kinase (PTK) are involved in signal transduction leading to the production of such a defensive response, we studied the HR in this plant system after treatment with G-protein activa...

Signal transduction: Gyrating protein kinases
Recently determined structures have linked histidine kinases with class II topoisomerases, the DNA repair enzyme MutL and the molecular chaperone Hsp90. This surprising finding may foreshadow a shift in our understanding of energy coupling mechanisms in signal transduction networks.
متن کاملThe Expression of Signal Regulatory Protein-alpha in Normal and Osteoarthritic Human Articular Cartilage and Its Involvement in Chondrocyte Mechano-transduction Response
Signal regulatory proteins (SIRP) belong to immunoglobulin super family (IgSF) and relate to integrin signaling cascades. It has been shown that SIRPa is expressed in a variety of cells including myeloid cells and neurons. In the present study the expression of this IgSF member in articular chondrocytes was investigated. Methods: Using a panel of anti-SIRPalpha antibodies, immunohistochemistry...
متن کاملP20: The Role of Protein Kinases in Memory
When an experience is encrypted into a long-lasting memory, it is believed that specific sets of neurons in the brain of the animal undergo changes including the strengthening of preexisting synapses and the growth and maintenance of new synaptic connections. These activity-dependent synaptic changes appear to require the coordination of a variety of cellular processes in spatially separated ce...
