* '''Ubiquitin TE''' or '''ubiquitin carboxyl-terminal hydrolase''' (USP) removes conjugated ubiquitin (Ub) from proteins thus regulating protein level by preventing their degradation. USP hydrolyze the peptide bond at the C-terminal glycine of ubiquitin (UB). The USPs are involved in the processing of poly-UB precursors and of ubiquinated proteins. USP contains catalytic domain surrounded several domains: Ub-like (UBL); Ub-associated (UBA); zinc finger-Ub-specific protease domain (UBP or DUSP); TRF homology domain. | * '''Ubiquitin TE''' or '''ubiquitin carboxyl-terminal hydrolase''' (USP) removes conjugated ubiquitin (Ub) from proteins thus regulating protein level by preventing their degradation.
