This is the C-terminal domain of Ubiquitin carboxyl-terminal hydrolase 47 (USP47), a ubiquitin-specific protease involved in deubiquitinating of monoubiquitinated DNA polymerase beta (Polbeta), being required for its stability and, therefore, plays a role in DNA base excision repair (BER). The C-terminal domains in USPs mediate protein- protein interactions.
