General annotation (Comments)

Function

Cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MYD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response By similarity.

Subunit structure

Belongs to the lipopolysaccharide (LPS) receptor, a multi-protein complex containing at least CD14, LY96 and TLR4. Binding to bacterial LPS leads to homodimerization. Interacts with LY96 via the extracellular domain. Interacts with MYD88 and TIRAP via their respective TIR domains. Interacts with NOX4 By similarity. Interacts with CNPY3 and HSP90B1; this interaction is required for proper folding in the endoplasmic reticulum. Interacts with MLK4; this interaction leads to negative regulation of TLR4 signaling By similarity.

Subcellular location

Membrane; Single-pass type I membrane protein By similarity.

Domain

The TIR domain mediates interaction with NOX4 By similarity.

Sequence similarities

Belongs to the Toll-like receptor family.

Contains 16 LRR (leucine-rich) repeats.

Contains 1 LRRCT domain.

Contains 1 TIR domain.
