The protein and mRNA levels of TRAF2
and the phosphorylation of JNK were markedly increased in the ConA group, and OA reduced the expression levels of TRAF2
and the activation of JNK (Figures 5(a)--5(c)).

Using the data from macrophages and fibroblasts, PathGen linked IL-27 to regulation of IL1[beta], TNF, and IL-6 through the IL12a and NF-[kappa]B/Rel pathways and to TRAF2
potentially through MDFI.
In addition, FBX07 binds to, and mediates ubiquitin conjugation to cIAP1 (cellular inhibitor of apoptosis protein 1) and TRAF2
(TNF receptor-associated factor 2), which leads to lowered activity of NF-[kappa]B (nuclear factor [kappa]B) (Kuiken et al., 2012).
At the same time, TNFR1 starts its own signaling associated with the RIP1-TRADD-TRAF2 complex, formed by the associated death domain receptor of TNF-R1 (TRADD), protein-1 that interacts with the receptor (RIP1), and factor 2 associated with TNF-R1 (TRAF2
Death deflected: IL-15 inhibits TNF-alpha-mediated apoptosis in fibroblasts by TRAF2
recruitment to the IL-15R-alpha chain.
Binding to TNF-R1 activates apoptotic and necrotic pathways through a signaling cascade involving multiple proteins, including TNF-R1-associated death domain protein (TRADD); TNF receptor-associated factor 2 (TRAF2
); and caspases 8, 3, and 7.
p43 could recruit signaling proteins, such as TRAF2
and RIP1, and activates the NF-kB pathway (Kataoka & Tschopp, 2004).
La activacion de TNFR1 resulta del reclutamiento de la proteina TRADD con la asociacion de las proteinas TRAF2
(factor 2 asociado a la proteina receptora de TNF[alfa]) o con FADD (proteina adaptadora que contiene un dominio de muerte citosolico); TRAF2
media la activacion de NF[kappa]B, mientras que FADD interactua con pro-caspasa 8, activandola.
, -5, and -6 all bind to RANK, but of these only TRAF6 appears to be essential in osteoclasts formation.
