Proximity biotinylation of NCI-H226 cells by EGFR-FabID


ABSTRACT: NCI-H226 cells were pretreated with DMSO or gefitinib and unstimulated or stimulated with EGF. Then AGIA-FabID or EGFR-FabID were added to the cells in three biological replicates. Cell lysates were subjected to methanol-chloroform precipitation and digested with trypsin. Biotinylated peptides were purified by Tamavidin 2-REV and identified by LC-MS/MS analysis.

Receptor proteins, such as epidermal growth factor receptor (EGFR), interact with other proteins in the extracellular region of the cell membrane to drive intracellular signalling. Therefore, analysis of extracellular protein-protein interactions (exPPIs) is important for understanding the biological function of receptor proteins. Here, we present an approach using a proximity biotinylation enzyme (AirID) fusion fragment of antigen binding (FabID) to analyse the proximity exPPIs of EGFR. AirID w  ...[more]
