Abstract

Identifying ligands for receptors in live cells can provide valuable information, providing insight into signaling pathways as well as drug targets, but these interactions can be difficult to detect and quantify. Frei et al. now report a trifunctional chemoproteomic reagent called TRICEPS that binds glycosylated receptors on live cells and allows for the purification of the ligand-receptor complex and identification of receptor-derived peptides by MS. TRICEPS contains three functional groups: an N-hydroxysuccinimide ester for ligand conjugation, a protein..
