Scientific Background: IRAK4 is a protein-serine/threonine kinase of the TKL group and IRAK family .It plays a critical role in initiating innate immune response against foreign pathogens. It is involved in Toll-like receptor (TLR) and IL-1R signalling pathways, and is rapidly recruited by MYD88 to the receptor-signalling complex upon TLR activation to form the Myddosome together with IRAK2. It phosphorylates initially IRAK1, thus stimulating the kinase activity and intensive autophosphorylation of IRAK1. It 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. IRAK4 phosphorylates TIRAP to promote its ubiquitination and subsequent degradation. It phosphorylates NCF1 and regulates NADPH oxidase activation after LPS stimulation.
