OTUD5 inhibits XRCC5. 3 / 3

reach
"21 In addition, OTUD5 promotes DNA damage repair by inhibiting Ku80 degradation or regulating FACT‐dependent transcription at damaged chromatin."

reach
"This suggests the possibility that OTUD5 is directly phosphorylated by ATM to function as an amplifier of ATM-dependent DDR signaling in a potential positive-feedback circuit, resembling its role in mTOR signaling.In the context of DNA repair, OTUD5 has been suggested to promote NHEJ by counteracting the degradation of Ku80, a core NHEJ factor, in certain cell lines ."

reach
"OTUD5 also stabilises Ku80, loss of OTUD5 reduces NHEJ repair efficiency [11] (Figure 2)."
