A20 zinc finger protein is a negative regulator of tumor necrosis factor (TNF)-induced signaling pathways leading to apoptosis, stress response and inflammation. A20 has been shown to bind to TNF-receptor-associated factor 2 (TRAF2) and 14-3-3 chaperone proteins. Our data indicate that the zinc finger domain of A20 is sufficient and that neither TRAF2 nor 14-3-3 binding is necessary for the inhibitory effects of A20. Mutations in the 14-3-3 binding site of A20 did, however, result in a partial cleavage of A20 protein suggesting that 14-3-3 chaperone proteins may stabilize A20. Furthermore, we show that A20 acts early in TNF-induced signaling cascades blocking both TNF-induced rapid activation of c-Jun N-terminal kinase and processing of the receptor-associated caspase-8. Taken together our data indicate that the zinc finger domain of A20 contains all necessary functional domains required for the inhibition of TNF signaling and that A20 may function at the level of the receptor signaling complex.

A20 zinc finger protein inhibits TNF-induced apoptosis and stress response early in the signaling cascades and independently of binding to TRAF2 or 14-3-3 proteins
