TIRAP (mouse)

TIRAP an adapter protein involved in the TLR4 signaling pathway in the innate immune response. Acts via IRAK2 and TRAF-6, leading to the activation of NF-kappa-B, ERK1, ERK2 and JNK, resulting in cytokine secretion and the inflammatory response. Homodimerizes. Also forms heterodimers with MyD88. Binds to TLR4 and IRAK2 via their respective TIR domains. Binds to PKR and TBK1. Does not interact with IRAK1, nor TLR9. Genetic variations in TIRAP can influence susceptibility or resistance to infectious diseases, including invasive pneumococcal disease, malaria and tuberculosis. Three isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
