IRF3/7 activates OTUD4. 2 / 2
| 2

reach
"Viral infection leads to the IRF3/7 dependent upregulation of OTUD4 which interacts with MAVS to remove K48 linked polyubiquitin chains, thereby maintaining MAVS stability and promoting innate antiviral signaling."

reach
"Degradative ubiquitination is counteracted by DUBs, as shown for ovarian tumor family deubiquitinase 4 (OTUD4), whose expression is increased by IRF3/7 in a positive-feedback loop (Liuyu et al., 2019)."
