Summary
TICAM1 adaptor protein is displaced from TICAM2 by a splice variant of TICAM2, TAG, resulting in the negative regulation of the MyD88-independent TLR4 pathway.
TICAM1 (TRIF)-dependent activation of CASP8 is involved in pro-apoptotic signalling through TLR3 and this under the control of inhibitor of apoptosis proteins in melanoma cells.
TICAM1 preferentially activates the IFN-beta promoter in the Toll-like receptor signalling, particularly in the MyD88-independent pathway.
TICAM1 (TRIF) recruits TRAF6-TAK1-TAB2 to TLR3 through its TRAF6-binding site, which is required for NF-kappaB but not IRF3 activation. TLR3/TICAM1-mediated NF-kappaB and IRF3 activation is induced by double-stranded RNA.
TICAM-1 is an adaptor molecule that participates in TLR3-mediated interferon-beta induction.
TICAM1 and TICAM2 both function in LPS-TLR4 signalling to regulate the MyD88-independent pathway during the innate immune response to LPS.
TICAM1 and TICAM2 form an adaptor complex that plays a crucial role in LPS-TLR4-mediated activation of IFN-beta.
The TICAM1 signalling pathway in murine dendritic cells is crucial for dsRNA-mediated natural killer cell activation. (Demonstrated in murine model)
TICAM1 deficiency results in the impairment of LPS-stimulated TNF-alpha protein translation. (Demonstrated in murine model)
TICAM1 is crucial for NLRP3 inflammasome activation in response specific to viable, but not heat-killed, E. coli infections. (Demonstrated in murine model)
TICAM1 is proteolytically cleaved by Enterovirus 71 3C to inhibit the induction of innate immunity by TLR3-signalling. TICAM1 cleavage results in the inhibition of NFkB and IFN-beta promoter activation.
TICAM1 forms a dsRNA sensor complex with components DDX1, DDX21 and DHX36 to trigger the type I interferon and cytokine response to poly I:C, influenza A virus, and reovirus. (Demonstrated in murine model)
TICAM1 is a potent negative regulator of TLR agonist-triggered immune responses, specifically suppressing IL12 in dendritic cells and IFNG in natural killer cells. (Demonstrated in mouse)
TICAM1 is a potent negative regulator of TLR agonist-triggered immune responses, specifically suppressing IL12 in dendritic cells and IFNG in natural killer cells. (Demonstrated in mouse)
TICAM1-TLR3-mediated signalling pathway plays an essential role in the anti-viral response against poliovirus infection. (Demonstrated in mouse)
TICAM1 plays a role in host resistance to Gram-negative enteropathogens. TICAM1-mediated protective immunity is orchestrated by macrophage-induced IFN-beta and natural killer cell production of IFN-gamma. (Demonstrated in mice)
TICAM1 forms a complex with RIPK3 upon Toll-like receptors (TLR) 3 and 4 activation resulting in RIPK3-dependent but TNF-independent necrosis in macrophages. (Demonstrated in mouse)
TICAM1 (TRIF) enhances expression of Kaposiā??s sarcoma-associated herpesviral protein RTA.
The homotypic interaction of TICAM2 Toll/interleukin-1 receptor (TIR) domain is essential to form a scaffold for recruiting the TICAM1 TIR domain.

[Mus musculus] High-potency Tlr4 agonists can act as clinically useful vaccine adjuvants by selectively activating Ticam1-dependent immunostimulatory signalling events and only weakly activating potentially harmful Myd88-dependent inflammatory responses.
[Mus musculus] Myd88 and Ticam1 pathways differently regulate Tlr4-induced immune responses in B cells.
[Mus musculus] Adaptor proteins Ticam1 and Ticam2 have a novel function in Tlr2-mediated signal transduction.
[Mus musculus] Ticam1 but not Myd88 signalling is critical for the Trl4 protective adjuvant effect in neonates; where Ticam1(-/-) but not Myd88(-/-) neonates are highly susceptible to Escherichia coli peritonitis and bacteremia.
[Mus musculus] Wdfy1 is a crucial adaptor protein in the Tlr3/4 signalling pathway. Wdfy1 interacts with Tlr3 and Tlr4 and mediates the recruitment of Ticam1 to these receptors.
[Mus musculus] Intracellular Sef/IL-17R (SEFIR) domain of Il17rd targets TIR adaptor proteins Myd88, Tirap, Ticam1, Ticam2 and Traf6 to inhibit TLR downstream signalling.
[Mus musculus] Yersinia pseudotuberculosis type III secretion system effector, YopJ, suppresses Trif(Ticam1)-dependent responses during infection of primary phagocytic cells, including dendritic cells and macrophages.
[Mus musculus] Ticam1-dependent type I interferon signalling in T cells is essential to Th1 lineage differentiation and reactivation of memory T cells. Ticam1 activated memory T cells facilitate local neutrophil influx and enhance bacterial elimination.
Entrez Gene
Summary This gene encodes an adaptor protein containing a Toll/interleukin-1 receptor (TIR) homology domain, which is an intracellular signaling domain that mediates protein-protein interactions between the Toll-like receptors (TLRs) and signal-transduction components. This protein is involved in native immunity against invading pathogens. It specifically interacts with toll-like receptor 3, but not with other TLRs, and this association mediates dsRNA induction of interferon-beta through activation of nuclear factor kappa-B, during an antiviral immune response.
