  • UbiQ-Probes

    Activity-based probes for deubiquitylases (DUBs) are based on ubiquitin with a C-terminal warhead designed to react with the active site cysteine residue present in most DUBs and potentially an N-terminal detection tag. The warhead serves an electrophile and reacts with the nucleophilic active site cysteine residue that is present in most DUBs. Our warheads: vinylmethyl ester (VME) propargylamide (PA) vinyl sulfone (VS) N-terminal detection tags: TAMRA Cy5 biotin HA DUB probes can be used for X-ray studies of DUB-Ub complexes or to ... read more »
