Tumor necrosis factor, alpha-induced protein 3 is a protein that in humans is encoded by the TNFAIP3 gene.
Contents
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 has been shown to inhibit NF-kappa B activation as well as TNF-mediated apoptosis. Knockout studies of a similar gene in mice suggested that this gene is critical for limiting inflammation by terminating TNF-induced NF-kappa B responses.
Interactions
TNFAIP3 has been shown to interact with TNIP1, TRAF1, TRAF2, IKBKG, TAX1BP1, YWHAB, YWHAZ, TRAF6 and YWHAH.
Association with rheumatoid arthritis
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. A third SNP, rs10499194 (T) is found less often in rheumatoid arthritis but this negative association may not be statistically meaningful.
