TNFAIP3 activates TLR. 4 / 4
| 4

reach
"Indeed, these 3 genes encodes for negative regulators of NF-κB signaling pathway: IL-1 receptor-associated kinase 3 (IRAK3) inhibits IRAK1/4 at the MyD88 complex; Tnfaip3 codes for the deubiquitinase A20, which removes poly-ubiquitin chains from TNF receptor-associated factor 6 (TRAF6); TRAF1 interferes with the linear ubiquitination of NEMO by the LUBAC complex.Several signaling molecules downstream of BCR synergize with TLR pathways to modulate the TLR response."

reach
"However, polymorphisms genes encoding proteins and transcription factors downstream of TLR activation, including TNFAIP3, TNIP1 and IRF5, correlate with lupus risk [XREF_BIBR, XREF_BIBR]."

reach
"Mice adoptively transferred with TNFAIP3 -/- x Myd88 -/- hematopoietic stem cells display decreased inflammatory activation in the intestine demonstrating that the control of immune cell TLR signaling by TNFAIP3 is also required for intestinal homeostasis XREF_BIBR."

reach
"83 In ABC DLBCL, biallelic inactivation of TNFAIP3 (by mutations, deletions or both) occurs in 30% of cases and can coexist with mutations in both MYD88 and CD79B, suggesting that inactivation of TNFAIP3 can enhance both BCR and TLR signalling pathways."
