IRAK4 (Interleukin-1 Receptor-Associated Kinase 4) is a serine/threonine kinase that serves as a key regulator of innate immune signaling. IRAK4 contains an N-terminal death domain and a C-terminal kinase domain. It is the first kinase activated downstream of TLRs and IL-1R, and it phosphorylates and activates IRAK1. IRAK4 is essential for responses to IL-1, IL-18, TLR2, TLR4, and TLR9 ligands. In the brain, IRAK4 mediates microglial activation and neuroinflammation. Genetic deficiency in IRAK4 results in immunodeficiency but also reduced inflammatory responses. IRAK4 is implicated in Alzheimer's disease (neuroinflammation), Parkinson's disease, and ALS. Selective IRAK4 inhibitors are being developed for inflammatory and autoimmune diseases, with potential applications in neurodegenerative conditions.
IRAK4 Protein is a IL-1 receptor-associated kinases. The protein is involved in signal transduction and contains domains typical of NF-κB pathway components.
IRAK4 is a serine/threonine kinase essential for TLR/IL-1R signaling. It phosphorylates IRAK1 and IRAK2, leading to TRAF6 activation. IRAK4 is upstream of IRAK1 in the signaling cascade. Unlike IRAK1, IRAK4 has essential kinase activity.
IRAK4 deficiency causes severe combined immunodeficiency with susceptibility to pyogenic bacteria.
PAXILLINE (IRAK4 inhibitor), experimental agents. Being explored for inflammatory diseases.
