Background
| Function | FUNCTION: Acts as a negative regulator of the Toll-like and IL-1R receptor signaling pathways. Attenuates the recruitment of receptor-proximal signaling components to the TLR4 receptor, probably through an TIR-TIR domain interaction with TLR4. Through its extracellular domain interferes with the heterodimerization of Il1R1 and IL1RAP. {ECO:0000269|PubMed:12925853, ECO:0000269|PubMed:14715412, ECO:0000269|PubMed:15866876, ECO:0000269|PubMed:25963006}. |
| Pathway | |
| Protein Families | Interleukin-1 receptor family |
| Tissue Specificity | Mainly expressed in epithelial tissues such as kidney, lung and gut. {ECO:0000269|PubMed:14715412, ECO:0000269|PubMed:21077278}. |
