TIR domain-containing adapter molecule 1 (Ticam1)

Involved in innate immunity against invading pathogens. Adapter used by TLR3 and TLR4 (through TICAM2) to mediate NF- kappa-B and interferon-regulatory factor (IRF) activation, and to induce apoptosis.

Ligand binding to these receptors leads to TRIF recruitment through its TIR domainname. Different protein- interaction motifs allow recruitment of the effector proteins TBK1, TRAF6 and RIPK1, which in turn, lead to the activation of transcription factors IRF3 and IRF7, NF-kappa-B and FADD respectively.
