TICAM-1 (TICAM1) Antibody – Rabbit Polyclonal

TRIF, or TICAM1, is a Toll/IL1R (MIM 147810) (TIR) domain-containing adaptor molecule, like MYD88 (MIM 602170) and TIRAP (MIM 606252), that induces interferon-beta (IFNB; MIM 147640), specifically interacts with TLR3 (MIM 603029), and activates nuclear factor kappa-B (NFKB; see MIM 164011).[supplied by OMIM]

TICAM1: an adaptor protein involved in innate immunity against invading pathogens. Associates with 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 results in TICAM1 recruitment through its TIR domain. Distinct 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. Interacts with the TIR domain of TLR3. Interacts with AZI2, TBK1, IRF3 and IRF7. Interacts with TICAM2 in TLR4 recruitment. Interaction with PIAS4 inhibits the TICAM1-induced NF-kappa-B, IRF and IFNB1 activation. Interacts with IKBKB and IKBKE. Interaction with SARM1 blocks TICAM1-dependent transcription factor activation. Interacts with TRAF3. Interacts with TRAFD1.
