Interleukin-1 receptor-associated kinase 1.


Available versions:

  • Wild type IRAK1
  • Dominant negative IRAK1 (see the "Details" tab)

Interleukin-1 receptor-associated kinases (IRAKs) are serine/threonine kinases that act as signal transduction mediators for the TLRs. The IRAK family consists of two active kinases, IRAK-1 and IRAK-4, and two inactive kinases, IRAK-2 and IRAK-M [1]. Upon stimulation, the adaptor MyD88 recruits IRAK-1, IRAK-2 and IRAK-4 to the receptor. IRAK-4 then phosphorylates IRAK-1 which dissociates from the receptor and interacts directly with TRAF-6 to relay the signal [2]. Subsequently, IRAK-1 undergoes autophosphorylation followed by degradation. IRAK-4 is an essential component of the IL-1, IL-18 and TLR signaling cascade [2-4].

IRAK1-DN version

Dominant negative IRAK1 (aa1-211) is a truncated form of IRAK1 that contains the N-terminal death domain but lacks the protein-kinase domain. This IRAK1-DN was shown to inhibit MyD88-induced NF-κB activation, suggesting that IRAK1 and MyD88 interact through their death domains [1].
