InnateDB Annotation
Summary
LY96 (MD-2) recognizes only exogenous pathogen-associated molecular patterns (PAMPs) when complexed with TLR2-CD14 or TLR4-CD14.
LY86 and CD180 interact directly with the TLR4 signalling complex, inhibiting its ability to bind microbial ligand.
LY96 is physically associated with TLR4 on the cell surface and confers responsiveness to lipopolysaccharide (LPS).
TLR4::LY96 functions as intracellular LPS sensor and triggers a unique set of LPS responses upon recognition of phagocytosed bacteria in macrophages. (Demonstrated in murine model)
Amino acid Phe126 of LY96 acts as a hydrophobic switch driving agonist-dependent contacts necessary for TLR4 dimerization and activation.
Morphine binds to LY96, triggering TLR4 oligomerization and induces neuroinflammation within the central nervous system.

Entrez Gene
Summary This gene encodes a protein which associates with toll-like receptor 4 on the cell surface and confers responsiveness to lipopolysaccyaride (LPS), thus providing a link between the receptor and LPS signaling. Studies of the mouse ortholog suggest that this gene may be involved in endotoxin neutralization. Alternative splicing results in multiple transcript variants encoding different isoforms.
