Toll-like receptor innate immune signaling pathway module

A compact Toll-like receptor (TLR) signaling module. Ligand-bound TLRs recruit TIR-domain adaptors such as MYD88, activate IRAK kinases and TRAF6 ubiquitin ligase scaffolds, and route the signal through TAK1/IKK and MAPK branches to NF-kappaB, AP-1, and inflammatory gene expression. The module is grounded in GO:0002224 and includes PTN anchors for TRAF6-family ubiquitin-ligase and innate-immune roles where local PAINT seed rows support them.

Connections

TLR/MYD88 complexes recruit and activate IRAK kinases and TRAF6.
IRAK/TRAF6-dependent ubiquitin scaffolds promote TAK1/IKK/MAPK activation.
Part 1: TLR ligand recognition and adaptor recruitment
TLR receptor-adaptor complexRegulatory Steptlr_receptor_adaptor_complex

Ligand-bound TLRs dimerize or reorganize their TIR domains and recruit adaptor proteins, most prominently MYD88 for the canonical pro-inflammatory branch.

Part 2: IRAK and TRAF6 signalosome
IRAK-TRAF6 ubiquitin signaling scaffoldRegulatory Stepirak_traf6_signalosome

MYD88 recruits IRAK kinases; activated IRAK proteins engage TRAF6, whose ubiquitin-ligase/scaffold activity promotes TAK1 and IKK/MAPK activation.
