Tumor necrosis factor, alpha-induced protein 3 or A20 is a protein that in humans is encoded by the TNFAIP3 gene.[5][6]

This gene was identified as a gene whose expression is rapidly induced by the tumor necrosis factor (TNF). The protein encoded by this gene is a zinc finger protein and a deubiquitinating enzyme, and has been shown to inhibit NF-kappa B activation as well as TNF-mediated apoptosis. The A20 protein is ancient, and homolog proteins can be found as far back as cnidaria (corals, jellyfish, anemones) with a conserved protein domain composition. [7] Using knockout mouse models of TNFAIP3 and its transcriptional repressor (i.e. KCHIP3), TNFAIP3 has been shown to be critical for limiting inflammation by terminating endotoxin- and TNF-induced NF-kappa B responses.[8] [9] In brief, deubiquitinase function of TNFAIP3 was shown to remove ubiquitin chains from VE-cadherin to prevent loss of VE-cadherin at the endothelial adherens junctions. [8]

Interactions[edit]

TNFAIP3 has been shown to interact with TNIP1,[10] TRAF1,[11][12] TRAF2,[11] IKBKG,[13] TAX1BP1,[14] YWHAB,[15] YWHAZ,[15][16] TRAF6[12][17] and YWHAH.[15][16]

Association with rheumatoid arthritis[edit]

The TNFAIP3 locus is implicated as a positively associated factor in rheumatoid arthritis (RA). The rs5029937 (T) and the rs6920220 (A) SNPs increase risk of RA by 20 to 40% respectively.[18] A third SNP, rs10499194 (T) is found less often in rheumatoid arthritis but this negative association may not be statistically meaningful.

Other diseases[edit]

An association with infantile onset intractable inflammatory bowel disease has also been reported.[19]
