Toll-like receptors (TLRs) play an essential role in the detection and elimination of invading pathogens. Recognition of microbial components by TLRs triggers activation of the innate immune system. Upon stimulation, these receptors interact with specific TIR domain-containing adaptor proteins. Five such adaptors have been discovered to date, MyD88, Trif (TIR-domain-containing adaptor inducing interferon-beta), TIRAP (TIR domain-containing adaptor protein)/Mal (MyD88 adaptor-like), TRAM (Trif-related adaptor molecule) and SARM (SAM and ARM-containing protein). MyD88 is common to all TLR-mediated pathways, which lead to the production of inflammatory cytokines, whereas TRIF mediates induction of IFN-beta in TLR3 and TLR4 signalling pathways. TIRAP/Mal is implicated in the TLR2- and TLR4-mediated MyD88-dependent signalling pathway. TRAM is specifically involved in the TLR4-mediated TRIF-dependent pathway. Thus, TIR domain-containing adaptors provide specificity of TLR signalling.

TIRAP_HUMAN

The innate immune system recognizes microbial pathogens through Toll-like receptors (TLRs), which identify pathogen-associated molecular patterns. Different TLRs recognize different pathogen-associated molecular patterns and all TLRs have a Toll-interleukin 1 receptor (TIR) domain, which is responsible for signal transduction. The protein encoded by this gene is a TIR adaptor protein involved in the TLR4 signaling pathway of the immune system. It activates NF-kappa-B, MAPK1, MAPK3 and JNK, which then results in cytokine secretion and the inflammatory response. Alternative splicing of this gene results in several transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

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.
