TRAF3

TRAF3

A gene on chromosome 14q32.32 that encodes TNF receptor-associated factor 3, which regulates NF-kappaB kinase and MAP kinase activation, plays a central role in regulating B-cell survival, and is part of signalling pathways leading to cytokine and interferon production. TRAF3 is required for normal antibody isotype switching from IgM to IgG, and it plays a role in T-cell dependent immune responses as well as antiviral responses. It is an essential constituent of several E3 ubiquitin-protein ligase complexes and may promote Lys-63-linked ubiquitination of target proteins. It inhibits NF-kappaB activation in response to LTBR stimulation, as well as TRAF2-mediated NF-kappaB activation, and it downregulates proteolytic processing of NFKB2 and NF-kappaB activation. It promotes ubiquitination and proteasomal degradation of MAP3K14.

Then, MAVS is positioned on the mitochondrial outer membrane and recruits TRAF3, which can phosphorylate IRF3/IRF7 (IFN regulatory factor) when ubiquitin is terminated which starts the type I IFN antiviral immune response [34].
Meanwhile, TRIF also activates TRAF3 which recruits IKK-related kinases (TBK1 and IKKe) and IKK[gamma] for IRF3 phosphorylation, which translocates into the nucleus inducing the expression of type IIFN genes [2, 41].
By downregulating tumor necrosis factor-associated factor 3 (TRAF3) protein expression, miR-455 played a vital role in protecting neuronal cells from death [19].

The stimulation of TLR7 and TLR9 with their respective ligand results in the formation of a complex constituted by MyD88, IRAK-4, TRAF6, TRAF3, IRAK-1, IKK-[kappa], and IRF7 re sponsible for the activation of IRF7, which once phosphorylated is translocated to the nucleus and regulates the expression of type-I IFN.
This occurs through IRF7 activation by IRAK-1 phosphorylation in a MyD88, IRAK-1, TRAF3, IKK[alpha], and IRK7 complex [77].
The cytoplasmic domain of Fn14 contains a phylogenetically conserved binding motif, and TRAF1, TRAF2, TRAF3, and TRAF5 are able to bind to this site [3].
Recently it has been published that TRAF-2 controls the fate of IRF5 and c-Rel by proteasomal degradation via TRAF3 and cIAP.
