Application【应用】 | KB03-SLF is an electrophilic PROTAC developed in the Cravatt lab and is useful for the discovery of ligandable E3 ligases, an area of interest for the targeted protein degradation (TPD) field seeking to map out and utilize a larger repertoire of the available human E3 ligases. This bifunctional tool compound comprises a synthetic ligand for FKBP12 (SLF) on one end and scout fragment 914975 on the other end. Scout fragments are electrophiles that covalently modify targetable cysteine residues on proteins, an approach that has been scaled to globally quantitate Cys reactivity across human proteomes and cells. When SLF and the electrophilic fragment are fused together, monitoring the levels of FKBP12 in cells may indicate scout-mediated FKBP12 degradation, for which follow-up studies would validate the mechanism of FKPB12 depletion and any targets to which the scout fragment is covalently bound. Scout-bound proteins leading to FKBP12 (or other targets) depletion discovered by this strategy will further expand the communal TPD toolbox. Due to the reactive nature of the scout fragment, other proteins will also be modified, so careful controls and validation should be considered. This proteomic approach to E3 discovery was demonstrated by Zhang et al in the discovery that DCAF16 mediated nuclear FKBP12 degradation via KB02-SLF. Additional electrophilic PROTACs were developed incorporating scout fragments with broad cysteine reactivity:
