"On the other hand, we also found 13 DUBs that were recruited to DNA damage sites but gave only marginal DSB repair defects upon siRNA depletion, including OTUB1, a negative regulator of the UBE2N (UBC13) ubiquitin E2 enzyme 24, USP44 that is reported to antagonize RNF168 dependent ubiquitylation 25, and OTUB2 that functions in repair-pathway choice 26 (XREF_FIG, XREF_FIG, and XREF_FIG), suggesting that some of the additional DUBs we identified might be negative DDR regulators and/or be involved in repair-pathway choice."
