OTUD5 deubiquitinates TRAF3. 14 / 14

reach
"However, it is uncertain whether DUBA also deubiquitinates TRAF3 in rainbow trout through a similar mechanism."

reach
"DUBA interacts with and de-ubiquitinates TRAF3, thereby attenuating TLR dependent and TLR independent antiviral responses XREF_BIBR."

reach
"For example, the deubiquitinase DUBA reverses TRAF3 ubiquitination, disconnecting TRAF3 from its substrates TBK1 and IKKepsilon XREF_BIBR."

reach
"Furthermore, OTUD5 deubiquitylates TRAF3 resulting in diminished type I interferon and interleukin-10 responses [XREF_BIBR]."

reach
"Indeed, the blockade of DUBA-mediated deubiquitination of TRAF3 by DUBA-specific siRNA cancelled the negative regulatory effects of NOD2 on DSS-induced colitis in mice treated with CpG, and mice treated with DUBA-siRNA displayed severe DSS-induced colitis even after repeated MDP injections (67, 68)."

reach
"Two close relatives of DUBA, OTUB1 and OTUB2, were shown to reduce TRAF3 ubiquitination coupled with decreased anti-viral signaling responses in Sendai virus infected HEK 293T cells."

"TRAF3 is an E3 ubiquitin ligase that preferentially assembled lysine-63-linked polyubiquitin chains. DUBA selectively cleaved the lysine-63-linked polyubiquitin chains on TRAF3, resulting in its dissociation from the downstream signaling complex containing TANK-binding kinase 1."

reach
"For example, TNFAIP3, CYLD, USP3, USP4, USP15, USP25, and OTUD5 deubiquitinate key components of the IFN production pathway, including RIG-I, TRAF2, TRAF3, TRAF6, RIP1, and TRIF (reviewed in [93,94])."

reach
"TRIAD3A dependent TRAF3 proteasomal destruction, like TRAF3 de-ubiquitination by DUBA, halts the activation of TBK1 and IKKepsilon and subsequent IFN production."

reach
"DUBA deubiquitinates TRAF3 to down-regulate its interaction with TBK1 and consequent activation of IRF-3."

reach
"In fact, DUBA physically interacts with TRAF3 and inhibits the self-ubiquitination of TRAF3."

reach
"Interestingly, the newly identified cellular DUB, DUBA, inhibits the ubiquitination of TRAF3, an adaptor of RIG-I signaling, and negatively regulates the type I IFN signaling pathway ."

reach
"Cellular protein DUBA specifically deubiquitinates TRAF3 that is critical for activation of IRF3, resulting in inhibiting phosphorylation of IRF3."
