29 / Multi-probe photoproximity labeling of the EGFR interactome in glioblastoma using red-light
F. Tong, W. Zhou, M. Janiszewska, C. P. Seath
J. Am Chem. Soc. 2025, Accepted​
​
In this manuscript we develop a carbene based probe for red-light photoproximity labeling by utilizing a sulfonium stabilized diazo group. We then exploit this method to study the interactome of EGFR through different resections obtained from a heterogeneous GBM tumor and show that EGFR has a unique interactome in brain infiltrates in GBM when compared to non-brain cancers and even the core of the same brain tumor.

In this collaboration with the Bao lab we identified the protein target of the small molecule ES5 using CETSA. This represents proof of concept that targeting ANXA6 with small molecules can greatly enhance mRNA delivery - a significant barrier to the development of RNA based therapeutics.
