Furthermore, TRAF1 has been associated with an increased risk of RA, however, the exact mechanisms regarding its role in RA are still unclear. Therefore, isolating its opposing effects on NF-B activation would provide an excellent model to study the exact role of TRAF1 in-vivo and in disease states such as RA and other inflammatory diseases, where multiple signaling pathways are involved. Since downstream of TLRs, TRAF1 negatively regulates NF-B by sequestering the Linear-Ubiquitin Chain Assembly Complex (LUBAC), we developed various TRAF1 truncations and mutants and by utilizing co-immunoprecipitation determined the exact protein-to-protein interaction between TRAF1 and LUBAC components. This will help create a TRAF1 mutant that does not associate with LUBAC, while maintaining its role in TNFR and other signaling pathways.Author owns copyright, except where explicitly noted.
