RIP1 polyubiquitination was induced upon TNF- or poly(I-C) treatment of the macrophage cell line RAW264.7 and the U373 astrocytoma line (Cusson-Hermance et al 2005). These workers have suggested that RIP1 may use similar mechanisms to induce NF-kB in the TNFR1- and Trif-dependent TLR pathways.

RIP1 modification with Lys-63 polyubiquitin chains was shown to be essential for TNF-induced activation of NF-kB (Ea et al. 2006). It is thought that TRAF family members mediate this Lys63-linked ubiquitination of RIP1 (Wertz et al. 2004, Tada et al 2001, Vallabhapurapu and Karin 2009), which may facilitate recruitment of the TAK1 complex and thus activation of NF-kB. Binding of NEMO to Lys63-linked polyubiquitinated RIP1 is also required in the signaling cascade from the activated receptor to the IKK-mediated NF-kB activation (Wu et al. 2006).
