Function

[IRAK4_MOUSE] Serine/threonine-protein kinase that plays a critical role in initiating innate immune response against foreign pathogens. Involved in Toll-like receptor (TLR) and IL-1R signaling pathways. Is rapidly recruited by MYD88 to the receptor-signaling complex upon TLR activation to form the Myddosome together with IRAK2. Phosphorylates initially IRAK1, thus stimulating the kinase activity and intensive autophosphorylation of IRAK1. Phosphorylates E3 ubiquitin ligases Pellino proteins (PELI1, PELI2 and PELI3) to promote pellino-mediated polyubiquitination of IRAK1. Then, the ubiquitin-binding domain of IKBKG/NEMO binds to polyubiquitinated IRAK1 bringing together the IRAK1-MAP3K7/TAK1-TRAF6 complex and the NEMO-IKKA-IKKB complex. In turn, MAP3K7/TAK1 activates IKKs (CHUK/IKKA and IKBKB/IKKB) leading to NF-kappa-B nuclear translocation and activation. Alternatively, phosphorylates TIRAP to promote its ubiquitination and subsequent degradation. Phosphorylates NCF1 and regulates NADPH oxidase activation after LPS stimulation suggesting a similar mechanism during microbial infections (By similarity).

Publication Abstract from PubMed

IL-1R-associated kinase (IRAK) 4 is an essential component of innate immunity. IRAK-4 deficiency in mice and humans results in severe impairment of IL-1 and TLR signaling. We have solved the crystal structure for the death domain of Mus musculus IRAK-4 to 1.7 A resolution. This is the first glimpse of the structural details of a mammalian IRAK family member. The crystal structure reveals a six-helical bundle with a prominent loop, which among IRAKs and Pelle, a Drosophila homologue, is unique to IRAK-4. This highly structured loop contained between helices two and three, comprises an 11-aa stretch. Although innate immune domain recognition is thought to be very similar between Drosophila and mammals, this structural component points to a drastic difference. This structure can be used as a framework for future mutation and deletion studies and potential drug design.
