FRET-based imaging of transbilayer movement of pepducin in living cells by novel intracellular bioreductively activatable fluorescent probes

To elucidate the mechanisms of direct transmembrane penetration of pepducins, which are artificial lipopeptide G protein-coupled receptor (GPCR) modulators, we developed two types of FRET-based probes, Pep13-FL-SS-Dab (13) targeting the inner leaflet of the lipid bilayer and Pep13-Dab-SS-FL (14) tar...
