Biochem/physiol Actions

EN523 is a cell-permeable covalent ligand that selectively modifies a non-catalytic, allosteric cysteine C23 in the K48 ubiquitin-specific deubiquitinase OTUB1. EN523 does not inhibit OTUB1 deubiquitination activity and serves as OTUB1 recruiter.

Many diseases are driven by proteins that are aberrantly ubiquitinated and degraded. These diseases would be therapeutically benefited by targeted protein stabilization (TPS). Here we present deubiquitinase-targeting chimeras (DUBTACs), heterobifunctional small molecules consisting of a deubiquitinase recruiter linked to a
