Inhibition of Basal FGF Receptor Signaling by Dimeric Grb2
Receptor tyrosine kinase activity is known to occur in the absence of extracellular stimuli. Importantly, this "background" level of receptor phosphorylation is insufficient to effect a downstream response, suggesting that strict controls are present and prohibit full activation. Here a mechanism is described in which control of FGFR2 activation is provided by the adaptor protein Grb2. Dimeric ...
متن کاملRegulation of nutrient metabolism by nuclear receptor/FGF signaling pathways
The regulation of metabolism in fed and fasted states is governed by hormonal and nutrient-derived signals that are mediated in part by nuclear receptors. Just as insulin and glucagon help the body store and mobilize energy through their membrane receptors, nutrient-derived lipids activate their cognate nuclear receptors (e.g., FXR and PPARs) to govern transcriptional programs involved in energ...
متن کاملA Lipid-Anchored Grb2-Binding Protein That Links FGF-Receptor Activation to the Ras/MAPK Signaling Pathway
Activation of the Ras/MAPK signaling cascade is essential for growth factor-induced cell proliferation and differentiation. In this report, we describe the purification, cloning, and characterization of a novel protein, designated FRS2, that is tyrosine phosphorylated and binds to Grb2/Sos in response to FGF or NGF stimulation. We find that FRS2 is myristylated and that this modification is ess...
متن کاملEndothelial FGF receptor signaling accelerates atherosclerosis.
Members of the fibroblast growth factor (FGF) family have been clinically applied to the treatment of ischemic diseases because of their strong angiogenic actions. Although tissue ischemia is predominantly caused by atherosclerosis, the roles of endothelial FGF receptors (FGF-Rs) in atherosclerosis remain obscure. We generated endothelial cell (EC)-targeted constitutively active FGF-R2-overexpr...
متن کاملInhibition of Interleukin 7 Receptor Signaling by Antigen Receptor Assembly
After the productive rearrangement of immunoglobulin (Ig) heavy chain genes, precursor (pre-)B lymphocytes undergo a limited number of cell divisions in response to interleukin (IL)-7. Here, we present evidence that this phase of IL-7-dependent expansion is constrained by an inhibitory signal initiated by antigen receptor assembly. A line of pre-B cells from normal murine bone marrow that expre...
