Tumor necrosis factor alpha-induced protein 3.


The zinc finger protein A20, also called tumor necrosis factor, alpha-induced protein 3 (TNFAIP3), is a TNF- and IL-1-inducible protein that negatively regulates NF-kB-dependent gene expression. A20 is encoded by an immediate early response gene whose expression is induced by different inflammatory stimuli. A20 inhibits NF-kB activation induced by the TLR2 ligand PGN or the TLR4 ligand LPS [1,2], as well as IFN-beta transcription triggered by the TLR3 ligand ds RNA [3], the inhibition taking place at the level of TRAF6 [4]. Thus A20 acts as a negative regulator of TLR-mediated inflammatory responses, thereby protecting the host against harmful overresponses to pathogens.
