Supplementary information

IRAK4 also known as Interleukin-1 receptor-associated kinase 4 is an important protein with an approximate molecular mass of 51 kDa. This protein is a significant part of the signaling cascade initiated by the Interleukin-1 receptor (IL-1R) and Toll-like receptors (TLRs). Expressed in a variety of tissues including the spleen thymus and lung IRAK4 is involved in innate immune responses. The presence of IRAK4 protein facilitates the downstream signaling pathways that activate the transcription factors responsible for inflammatory cytokine production.
Biological function summary

IRAK4 plays an important role in mediating signaling in the innate immune system by forming complexes with other proteins such as IRAK-1. These complexes propagate signals that result in the activation of transcription factors like NF-kB and AP-1 which regulate the expression of inflammatory genes. Through these mechanisms IRAK4 influences the body's ability to respond to infections and stresses. Its critical involvement in these signaling pathways highlights its importance in maintaining immune homeostasis.

Pathways

IRAK4 is a pivotal player in the Toll-like receptor and IL-1 receptor signaling pathways which are central to the host defense against pathogens. It functions upstream activating the MyD88-dependent pathway resulting in the recruitment and phosphorylation of other kinases such as IRAK-1 and TRAF6. These interactions trigger the NF-kB signaling cascade thereby enhancing pro-inflammatory cytokine production that is essential for initiating immune responses.

Mutations or dysregulation of IRAK4 are linked to increased susceptibility to recurrent bacterial infections and sepsis. Patients with IRAK4 deficiency have impaired NF-kB activation leading to a weakened inflammatory response. Additionally overexpression of IRAK4 has been observed in certain autoimmune diseases such as rheumatoid arthritis where the persistent activation of TLR signaling contributes to chronic inflammation. The role of IRAK4 in these disorders ties closely with its interaction with proteins like TRAF6 influencing disease development and progression.

Target data

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 (PubMed : 17878374). 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.
