USP10
USP10, or ubiquitin specific peptidase 10, is a human deubiquitinating enzyme, first described in 2001, that removes ubiquitin from proteins and stabilizes p53 after DNA damage.
USP14
USP14 (ubiquitin-specific peptidase 14, Ubp6) is a human proteasome-associated deubiquitinase at 18p11.32 that trims ubiquitin chains to regulate protein degradation; target of IU1-series inhibitors in cancer and neurodegeneration research.
USP15
