Redox‐Based Probes for Protein Tyrosine Phosphatases

Abstract

Three in one: The design strategy for redox-based probes (RBPs) that detect the reversible oxidation of protein tyrosine phosphatases (PTPs) includes a “warhead” that forms a covalent adduct with the oxidized active site cysteine of PTPs, a synthetic module that directs binding to the PTP active site, and a chemical reporter tag used for the identification, purification, or direct visualization of the probe-labeled proteins (see picture).
