Interleukin-1 (IL-1) receptor-associated kinase (IRAK) plays an important role in the sequential formation and activation of IL-1-induced signaling complexes. Previous studies showed that IRAK is recruited to the IL-1-receptor complex, where it is hyperphosphorylated. We now find that the phosphorylated IRAK in turn recruits TRAF6 to the receptor complex (complex I), which differs from the previous concept that IRAK interacts with TRAF6 after it leaves the receptor. IRAK then brings TRAF6 to TAK1, TAB1, and TAB2, which are preassociated on the membrane before stimulation to form the membrane-associated complex II. The formation of complex II leads to the phosphorylation of TAK1 and TAB2 on the membrane by an unknown kinase, followed by the dissociation of TRAF6-TAK1-TAB1-TAB2 (complex III) from IRAK and consequent translocation of complex III to the cytosol. The formation of complex III and its interaction with additional cytosolic factors lead to the activation of TAK1, resulting in NF-kappaB and JNK activation. Phosphorylated IRAK remains on the membrane and eventually is ubiquitinated and degraded. Taken together, the new data reveal that IRAK plays a critical role in mediating the association and dissociation of IL-1-induced signaling complexes, functioning as an organizer and transporter in IL-1-dependent signaling.
