Interleukin-1 receptor-associated kinase 3 (originally IRAK-M) is an enzyme that in humans is encoded by the IRAK3 gene.[1][2] The IRAK family of proteins consists of two active serine/threonine kinases IRAK-1 and IRAK-4, as well as two inactive kinases IRAK-2 and IRAK-3. The activity of IRAK-3 is induced by toll-like receptor and interleukin-1 receptor signaling. IRAK-3 acts as a negative regulator for downstream signaling through these pathways by preventing the phosphorylation of IRAK-1 and IRAK-4 or by inhibiting their dissociation from the Mydd88 complex. [3] Using in vivo liposome-mediated delivery of CRISPR/Cas9 plasmid expressing IRAK3 gRNA, IRAK3 was shown to be responsible for endotoxin-induced expression of A20 and VE-cadherin in endothelial cells. Thus, IRAK3 is crucial for maintenance and repair of endothelial barrier after endotoxin-induced lung injury.[4]
