Crystal structure of mouse TLR4/MD-2/LPS complex
Template:ABSTRACT PUBMED 22532668
Disease
[TLR4_MOUSE] Note=The protein is encoded by the Lps locus, an important susceptibility locus, influencing the propensity to develop a disseminated Gram-negative infection.
Function
[TLR4_MOUSE] 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).[1] [LY96_MOUSE] Cooperates with TLR4 in the innate immune response to bacterial lipopolysaccharide (LPS), and with TLR2 in the response to cell wall components from Gram-positive and Gram-negative bacteria. Enhances TLR4-dependent activation of NF-kappa-B. Cells expressing both MD2 and TLR4, but not TLR4 alone, respond to LPS (By similarity).
About this Structure
