Abstract
Chemical cross-linking is well-established for investigating protein-protein interactions. Traditionally, photo cross-linking is used but is associated with problems of selectivity and UV toxicity in a biological context. We here describe, with live cells and under normal growth conditions, selective cross-linking of a furan-modified peptide ligand to its membrane-presented receptor with zero toxicity, high efficiency, and spatio-specificity. Furan-modified kisspeptin-10 is covalently coupled to its glycosylated membrane receptor, GPR54(KISS1R). This newly expands the applicability of furan-mediated cross-linking not only to proteinprotein cross-linking but also to cross-linking in situ. Moreover, in our earlier reports on nucleic acid interstrand cross-linking, furan activation required external triggers of oxidation (via addition of N-bromo succinimide or singlet oxygen). In contrast, we here show, for multiple cell lines, the spontaneous endogenous oxidation of the furan moiety with concurrent selective cross-link formation. We propose that reactive oxygen species produced by NADPH oxidase (NOX) enzymes form the cellular source establishing furan oxidation.
