Synthesis pass · prose summary of the discoveries below

IRAK1 is a serine/threonine kinase central to TLR/IL-1R innate immune signaling, functioning both as a catalytic enzyme and as a scaffolding platform that activates NF-κB, inflammasome, and antiviral pathways. Pre-associated with Tollip, IRAK1 is recruited to activated receptor complexes via MyD88, where it is activated through heterodimerization with phosphorylated IRAK4; once activated, IRAK1 dissociates and engages TRAF6 to drive NF-κB and MAPK signaling, phosphorylates Pellino E3 ligases to trigger K63-polyubiquitination of itself and coupling to NEMO/IKK, and phosphorylates the adaptor Mal to promote its degradation (PMID:8599092, PMID:10854325, PMID:17997719, PMID:20400509, PMID:29208712). Beyond canonical NF-κB activation, IRAK1 kinase activity directly links TLR stimulation to rapid NLRP3 inflammasome assembly independent of transcription, activates viperin's radical SAM activity to produce the antiviral nucleotide ddhCTP, and stabilizes MCL1 through TRAF6-mediated K63-ubiquitination (PMID:24379360, PMID:30872404, PMID:25642772). IRAK1's kinase-independent scaffolding function is essential for survival of MyD88-mutant lymphoma cells, and human IRAK1 deficiency selectively impairs TLR signaling in fibroblasts but is largely redundant in leukocytes (PMID:34279092, PMID:28069966).

2017 IRAK1 undergoes K48-linked ubiquitination at Lys134 mediated by β-TrCP, which facilitates membrane-to-cytoplasm trafficking of IRAK1 interacting partners TRAF6 and TAK1 and subsequent NF-κB/MAPK activation downstream of TLR9; glucocorticoid receptor physically interacts with IRAK1 and blocks β-TrCP-IRAK1 interaction, selectively suppressing TLR9-induced IRAK1 ubiquitination.
