Abstract
Hundreds of human proteins are modified by reversible palmitoylation of cysteine residues (S-palmitoylation), but the regulation of depalmitoylation is poorly understood. Here, we develop 'depalmitoylation probes' (DPPs), small-molecule fluorophores, to monitor the endogenous activity levels of 'erasers' of S-palmitoylation, acylprotein thioesterases (APTs). Live-cell analysis with DPPs reveals rapid growth-factor-mediated inhibition of the depalmitoylation activity of APTs, exposing a novel regulatory mechanism of dynamic lipid signaling.Entities:
