DESCRIPTION

Also known as IRAK3_HUMAN, IRAK3. Putative inactive protein kinase which regulates signaling downstream of immune receptors including IL1R and Toll-like receptors (PubMed:10383454, PubMed:29686383). Inhibits dissociation of IRAK1 and IRAK4 from the Toll-like receptor signaling complex by either inhibiting the phosphorylation of IRAK1 and IRAK4 or stabilizing the receptor complex (By similarity). Upon IL33-induced lung inflammation, positively regulates expression of IL6, CSF3, CXCL2 and CCL5 mRNAs in dendritic cells (PubMed:29686383). Monomer (PubMed:33238146). Homodimer; disulfide-linked (PubMed:33238146). May interact with IRAK4 (when phosphorylated) (PubMed:33238146). Interacts (when phosphorylated at Ser-110) with PIN1 (via WW domain) in response to IL33-mediated (but not TLR4 ligand LPS) dendritic cell stimulation (PubMed:29686383).
