The use of small molecule probes to study spatially separated stimulus-induced signaling pathways

Bioorg Med Chem Lett. 2012 Mar 1;22(5):2043-5. doi: 10.1016/j.bmcl.2012.01.024. Epub 2012 Jan 14.

Abstract

Simultaneous activation of signaling pathways requires dynamic assembly of higher-order protein complexes at the cytoplasmic domains of membrane-associated receptors in a stimulus-specific manner. Here, using the paradigm of cellular activation through cytokine and innate immune receptors, we demonstrate the proof-of-principle application of small molecule probes for the dissection of receptor-proximal signaling processes, such as activation of the transcription factor NF-κB and the protein kinase p38.
