MyD88, CT, Blocking Peptide (Myeloid Differentiation Marker 88, Myeloid Differentiation Primary Response Gene, Myeloid Differentiation Primary Response Protein MyD88)

Peptide corresponding to amino acids 279 to 296 of human MyD88 (CTKSWFWTRLAKALSLP) (5), which are identical to those of mouse.\n\nThe pro-inflammatory cytokine IL-1 induced cellular response requires IL-1 receptor complex including IL-1RI and IL-1RAcP. Recently, MyD88 was identified as an adapter molecule in the IL-1 signaling pathway (1). MyD88 associates with and recruits IRAK to the IL-1 receptor complex in response to IL-1 treatment and the dominant negative form of MyD88 attenuates IL-1R-mediated NF-kB activation. MyD88 is also employed as a regulator molecule by IL-18 receptor and human Toll receptor (2,3), which are members of the Toll/IL-1R family of receptors. \n\nTargeted disruption of the MyD88 gene results in loss of cellular responses to IL-1 and IL-18, and MyD88-deficient mice lack responses to bacterial product LPS that employs Toll-like receptors 2 and 4 (TLR2 and TLR4) as the signaling receptors. MyD88 is a general adapter protein for the Toll/IL-1R family of receptors and plays an important role in the inflammatory response induced by cytokines IL-1 and IL-18 and endotoxin. The MyD88 gene is expressed in many tissues.
