特徴

• 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.
• Association with MYD88 leads to IRAK1 phosphorylation by IRAK4 and subsequent autophosphorylation and kinase activation.
• 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 the interferon regulatory factor 7 (IRF7) to induce its activation and translocation to the nucleus, resulting in transcriptional activation of type I IFN genes, which drive the cell in an antiviral state.
• When sumoylated, translocates to the nucleus and phosphorylates STAT3.
