Multiple previously established signaling cascades in activated mast cells with quantitative proteomic data from MCP5 cells represented as heatmap bars beside individual proteins. These heatmap bars represent the change of abundance of phosphorylation on known mast cell signaling proteins through a timecourse of Fc receptor stimulation (as additionally portrayed in Figure 4a). a) FcεRI-mediated activation pathways. b) IL-3 receptor mediated pathway. c) A representative inhibitory pathway.
