IRAK4 (interleukin-1 receptor-associated kinase 4) protein contains a death domain and a kinase-like domain. IRAKs are mainly involved in toll-like receptors (TLRs) and interleukin-1 receptors (IL-1Rs) signaling. IRAK4 can activate NF-κB (nuclear factor κ B) and MAPK (mitogen activated protein kinase) pathways. It plays a crucial role in adaptive immunity and inflammatory responses. IRAK4 mRNA levels are higher in humans suffering from Vogt-Koyanagi-Harada (VKH) disease. Mutations in IRAK4 are associated with recurrent pyogenic bacterial infections in children.
