Abstract

Conjugation of proteins to AMP (AMPylation) is a prevalent post-translational modification (PTM) in human cells, involved in the regulation of unfolded protein response and neural development. Here we present a tailored pronucleotide probe suitable for in situ imaging and chemical proteomics profiling of AMPylated proteins. Using straightforward strain-promoted azide-alkyne click chemistry, the probe provides stable fluorescence labelling in living cells.
