Anti-MyD88

MyD88 (Myeloid differentiation factor) is an essential adaptor molecule in all TLR (Toll-like receptor) signaling pathways except TLR3. MyD88 is composed of an N-terminal (Death Domain) and a highly conserved C-terminal TIR (Toll/interleukin-1 Receptor) domain. It is found to stimulate IL-1R/IL18R-mediated signaling. MyD88-dependent signaling is also important in the regulation of innate as well as acquired immunity, in particular, T-cell responses, to various microbial pathogens. After activation of TLRs, MyD88 is phosphorylated and subsequently recruits IRAKs (IL-1R Associated Kinases) and other downstream proteins such as TRAF6, finally resulting in activation of the NF-kappaB (nuclear factor kappa B) pathway. Protein function: Adapter protein involved in the Toll-like receptor and IL-1 receptor signaling pathway in the innate immune response (PubMed:15361868, PubMed:18292575). Acts via IRAK1, IRAK2, IRF7 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (PubMed:15361868, PubMed:24316379, PubMed:19506249). Increases IL-8 transcription (PubMed:9013863). Involved in IL-18-mediated signaling pathway. Activates IRF1 resulting in its rapid migration into the nucleus to mediate an efficient induction of IFN-beta, NOS2/INOS, and IL12A genes. MyD88-mediated signaling in intestinal epithelial cells is crucial for maintenance of gut homeostasis and controls the expression of the antimicrobial lectin REG3G in the small intestine.
