USP7 deubiquitinates UVSSA. 1 / 1
1 |

"The central region of UVSSA, which contains the tumor necrosis factor receptor-associated factor (TRAF)-binding motif, is required for the interaction with the N-terminal TRAF domain of USP7. Here, we showed that UVSSA is mono-ubiquitinated in?vitro and identified a lysine residue (Lys414?) in UVSSA as the target of ubiquitination. The deubiquitination activity of USP7 was inhibited by the ubiquitin-conjugating enzyme UbcH6. Lys414?was also modified by poly-ubiquitin chains in?vivo.?"
