"First, CYLD inhibits NF- κ B signaling by deubiquitinating NF- κ B-positive regulators, such as TAK1 (TGF- β -activated Kinase 1), TRAF2 and NEMO/IKK γ . xref , xref Second, caspase 8-mediated cleavage of CYLD generates a survival signal, whereas the mutation of caspase 8-mediated cleavage site on CYLD switches cell survival to necrotic cell death in response to TNF α . xref Last but not least, CYLD interacts with and deubiquitinates RIP1. xref However, it is still controversial whether CYLD affects the ubiquitination of RIP1 in complex I or in the necrosome. xref , xref Given that the above DUBs can remove ubiquitin chains from RIP1, how is RIP1 ubiquitinated?"

"It was demonstrated by a biochemical study that CYLD has an ability to cleave not only Lys 63-linked ubiquitin chains, but also linear ubiquitin chains ( xref ), which discovery was followed up by a cellular signaling study showing that CYLD inhibits the NF-κB signaling by forming a complex with LUBAC ( xref )."

"It was initially believed that CYLD inhibited IFN signaling by deubiquitinating the PRR, RIG‐1, and downstream kinases TANK‐binding kinase 1 (TBK‐1) and inhibitor of NF‐κB kinase Ε (IKKΕ) xref ; but, surprisingly, IFN response to vesicular stomatitis virus in CYLD knockout mice or cells from these mice was abrogated. xref On the basis of these reports, TRAF3 and CYLD may serve similar functions after viral infection, namely, to inhibit NF‐κB and activate IFN."

"Furthermore, EAC also inhibited the cell survival signaling by enhancing the amount of I κ - α in cytoplasm and reducing the level and activity of nuclear factor (NF)- κ B in the nucleus, and subsequently attenuated the expression of
Bcl-X L in Hep G2 and PLC/PRF/5 cells [ xref ]."
