The Interleukin 1 receptor family (IL-1 R) comprises at least eleven members including IL-1 RI, IL-1 RII, IL-1 RAcP, ST2, IL 18 R alpha, IL-1 Rrp2, IL-18 R beta, IL-1RAPL 1 (TIGIRR 2/IL 1 R8), and TIGIRR-1 (IL-1 R9). All family members possess three immunoglobulin (Ig)-like domains in their extracellular region. Most members have an intracellular TIR (Toll-like receptor/IL-1 receptor signaling) domain that is also conserved in the Toll-like receptor family. The sequence of human SIGIRR predicts a 410 amino acid (aa) residue transmembrane glycoprotein that lacks signal peptide and contains a 118 aa single Ig extracellular domain, a transmembrane region and a 268 aa cytoplasmic tail with a TIR domain. The cytoplasmic tail of SIGIRR contains a C-terminal extention beyond the TIR domain which is also found in IL-1 R8, IL-1 R9, and Toll-like receptor family members but absent in other IL-1 receptor family members.

SIGIRR is widely expressed and is present in all cells and tissues examined. The ligand and signaling mechanism for SIGIRR has not been identified. It has been observed to modulate immune responses, colonic epithelial homeostasis and tumorigenesis. SIGIRR has been shown to interact with TRAF6.


The entire kit may be stored at -20°C for up to 1 year from the date of shipment. Avoid repeated freeze-thaw cycles. The kit may be stored at 4°C for up to 6 months. For extended storage, it is recommended to store at -80°C.
