What's a GeneRIF?

SLAMF1 is required for TLR4-mediated TRAM-TRIF-dependent signaling in human macrophages.
Title: SLAMF1 is required for TLR4-mediated TRAM-TRIF-dependent signaling in human macrophages.
Data suggest that endosomal localization of TICAM2 is essential for TLR4-mediated type I interferon-inducing signaling from endosomes; TICAM2 acts as scaffold protein and activates TICAM1; N-terminal myristoylation allows TICAM2 to anchor to endosomal membrane. (TICAM2 = toll like receptor adaptor molecule-2; TICAM1 = toll like receptor adaptor molecule-1; TLR4 = toll-like receptor 4) [REVIEW]
Title: Functional interfaces between TICAM-2/TRAM and TICAM-1/TRIF in TLR4 signaling.
Data show that Toll/IL-1R domain-containing adaptor molecule (TICAM)-2 possesses two conserved acidic amino acids, D91 and E92, which regulate TICAM-2 self-activation and signaling.
Title: Identification of a Regulatory Acidic Motif as the Determinant of Membrane Localization of TICAM-2.
Findings were SNPs in TICAM2 (P = 3.6 x 10(-6)) and IL1B (P = 4.3 x 10(-5)) associated with TB.
Title: Polymorphisms in TICAM2 and IL1B are associated with TB.
TRAM plays a role in TLR7 signaling through a novel signaling axis towards the activation of anti-viral immunity.
Title: The TIR-domain containing adaptor TRAM is required for TLR7 mediated RANTES production.
TRAM acts as a sorting adaptor not only for TLR4, but also for TLR2, to facilitate signaling to IRF7 at the endosome, which explains how TLR2 is capable of causing type I IFN induction.
Title: TRAM is required for TLR2 endosomal signaling to type I IFN induction.
A putative TRAF6-binding motif in TRAM may mediate a new TRAM function in TLR4 signaling in regulating inflammatory responses, distinct from its bridging TLR4 and TRIF. A TRAM E183A mutation abolished this.
Title: The TLR signaling adaptor TRAM interacts with TRAF6 to mediate activation of the inflammatory response by TLR4.
results suggest TLR adaptor molecules knockdown, such as MyD88 or TRAM, can decrease IL-6 and IL-8 mRNA and increase CXCL12 mRNA expression in HGF and HPDLF.
Title: MyD88 or TRAM knockdown regulates interleukin (IL)-6, IL-8, and CXCL12 mRNA expression in human gingival and periodontal ligament fibroblasts.
The homotypic interaction between TICAM-2 TIR is indispensable to present a scaffold for recruiting the monomeric moiety of the TICAM-1 TIR dimer.
Title: Structures and interface mapping of the TIR domain-containing adaptor molecules involved in interferon signaling.
induction of both IL-6 and IL-8 is associated with elevated TIRAP and reduced TRAM mRNA expression
Title: Human cytomegalovirus induces TLR4 signaling components in monocytes altering TIRAP, TRAM and downstream interferon-beta and TNF-alpha expression.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
