Abstrakt: Kanagy et al. combine biochemical and fluorescence microscopy methods to determine the interplay between positive and negative signaling molecules within the FcεRI signalosome. The results highlight the ability of ITAM-based signaling to respond to various ITAM phosphorylation patterns, Syk binding conformations, and the presence/absence of key regulatory molecules. These molecular mechanisms provide insight into how disparate immunoreceptors can utilize conserved signaling cascades to tailor their cellular outcomes.
