USP11 (ubiquitin carboxyl-terminal hydrolase 11) is a member of the ubiquitin specific proteases family (USPs) and is a protease that functions in the removal of conjugated ubiquitin from target proteins and polyubiquitin chains. The enzyme cleaves preferentially 'Lys-6' and 'Lys-63'-linked ubiquitin chains and is involved in regulating pathways that lead to NF-kappa-B activation by regulating IκB kinase α (1). USP11 also binds to p21, a cyclin-dependent kinase inhibitor and plays an important role in regulating cell-cycle progression and DNA damage responses.
