SIGIRR proteins function as negative regulators of Toll-like and IL-1R receptor signaling pathways. It inhibits the recruitment of signaling components to the TLR4 receptor through TIR domain interactions. SIGIRR Protein, Human (HEK293, Fc) is the recombinant human-derived SIGIRR protein, expressed by HEK293 , with C-hFc labeled tag.

Human

The SIGIRR protein acts as a negative regulator of the Toll-like and IL-1R receptor signaling pathways. It functions by inhibiting the recruitment of signaling components to the TLR4 receptor, likely through an interaction between their TIR domains. Furthermore, SIGIRR interferes with the heterodimerization of Il1R1 and IL1RAP through its extracellular domain. It interacts with various proteins including IL1R1, IRAK1, TLR4, TLR5, TLR9, TRAF6, and PALM3. Upon IL-1 stimulation, SIGIRR can be found in a complex consisting of IL1R1, SIGIRR, MYD88, IRAK1, and TRAF6. Similarly, upon stimulation with LPC, SIGIRR is present in a complex comprising TLR4, SIGIRR, MYD88, IRAK1, and TRAF6.
