pubmed:abstractText
The Crohn's disease and early onset sarcoidosis susceptibility protein, NOD2, coordinates innate immune signaling pathways. Because dysregulation of this coordination can lead to inflammatory disease, maintaining appropriate activation of the NOD2 signaling pathway is paramount in immunologic homeostasis. In this work, we identify the atypical tumor necrosis factor-associated factor (TRAF) family member, TRAF4, as a key negative regulator of NOD2 signaling. TRAF4 inhibits NOD2-induced NF-?B activation and directly binds to NOD2 to inhibit NOD2-induced bacterial killing. We find that two consecutive glutamate residues in NOD2 are required for interaction with TRAF4 and inhibition of NOD2 signaling because mutation of these residues abrogated both TRAF4 binding and inhibition of NOD2. This work identifies a novel negative regulator of NOD2 signaling. Additionally, it defines a TRAF4 binding motif within NOD2 involved in termination of innate immune signaling responses.
