Synthetic peptide from the unique amino-terminal end of the protein, conjugated to KLH (peptide was post-synthetically modified to achieve highest antigenicty before used for coupling to KLH using heterobifunctional cross linker).
Storage instructionsShipped at 4°C. Store at +4°C short term (1-2 weeks). Store at -20°C or -80°C. Avoid freeze / thaw cycle.
FunctionFunctions in LPS-TLR4 signaling to regulate the MYD88-independent pathway during the innate immune response to LPS. Also involved in IL1-triggered NF-kappa-B activation, functioning upstream of IRAK1, IRAK2, TRAF6, and IKBKB. Physically bridges TLR4 and TICAM1 and functionally transmits LPS-TRL4 signal to TICAM1.
Tissue specificityExpressed in spleen, prostate, testis, uterus, small intestine, colon, peripheral blood leukocytes, heart, placenta, lung, liver, skeletal muscle, and pancreas.
Sequence similaritiesContains 1 TIR domain.
DomainThe TIR domain mediates the interaction with TRAF6.
Post-translational modificationsPhosphorylated by PKCE in response to LPS. Phosphorylation is essential for its function. It is depleted from the membrane upon phosphorylation. Myristoylated. Required for membrane association which is critical for its ability to initiate efficient signaling.
Cellular localizationCytoplasm. Golgi apparatus. Cell membrane. Localized to the plasma membrane as a result of myristoylation. Phosphorylation on Ser-16 leads to its depletion from the membrane.
