  • 产品描述：

    IRAK4 is a key regulator of innate immune signaling that regulates IL1R and TLR-mediated responses to viral and bacterial pathogens, as well as sterile inflammatory products. It has scaffolding and kinase activity. Given the importance of IRAK4 in TLR signaling, its mutation causes NF-kappa B and MAPKs activation to be hindered. Humans with IRAK4 activity deficit have an autosomal recessive primary immune deficiency (PID), which causes them to be susceptible to a limited number of Gram-negative bacterial infections but not viral or fungal infections.

    The recombinant IRAK4 antibody expression is induced in mammalian cells transfected with a recombinant plasma vector. The recombinant plasma vector was constructed by inserting the gene coding for the antibody against IRAK4 into the plasma. The recombinant IRAK4 antibody was purified from the cell culture medium using Affinity-chromatography. It can react with samples containing IRAK4 protein from Human and has been validated for use in the ELISA, WB, FC.

  • 功能：
    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.

    3. IRAK-4 Arg12 is also essential for Myddosome assembly and signalling and we propose that phosphorylated Ser8 induces the N-terminal loop to fold into an alpha-helix. This conformer is stabilised by an electrostatic interaction between phospho-Ser8 and Arg12 and would destabilise a critical interface between IRAK-4 and MyD88. PMID: 27876844

Data suggest that IRAK4 activity regulates activation of IRF5, TAK1, and IKKB in monocytes; IRAK4 activation of TAK1-IKKB-IRF5 axis leads to induction of cytokines and interferons following TLR7/TLR8 stimulation. (IRAK4 = interleukin-1 receptor-associated kinase 4; IRF5 = interferon regulatory factor-5; TAK1 = MAPK kinase kinase 7; IKKB = I-kappa B kinase; TLR = toll-like receptor) PMID: 28924041
