Coding sequence in expression plasmid

Alias: A20, OTUD7C

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.

This gene is available in pUNO1 expression plasmid selectable with Blasticidin.
