Detection of IL1RAPL2 in HepG2 Human Cell Line by Flow Cytometry. HepG2 human hepatocellular carcinoma cell line was stained with Goat Anti-Human IL1RAPL2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1007, filled histogram) or control antibody (AB-108-C, open histogram), followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (F0108).
Detection of IL1RAPL2 in Hepa 1‑6 Mouse Cell Line by Flow Cytometry. Hepa 1-6 mouse hepatoma cell line was stained with Goat Anti-Human IL1RAPL2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1007, filled histogram) or control antibody (AB-108-C, open histogram), followed by Allophycocyanin-conjugated Anti-Goat IgG Secondary Antibody (F0108).
IL1RAPL2 in Human Skin. IL1RAPL2 was detected in immersion fixed paraffin-embedded sections of human skin using Goat Anti-Human IL1RAPL2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1007) at 3 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Goat IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC004). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to endotheliam cells in vasculature.

The Interleukin 1 receptor family (IL-1 R) comprises at least eleven members including IL-1 RI (IL-1 R1), IL-1 RII (IL-1 R2), IL-1 RAcP (IL-1 R3), ST2 (T1/IL-1 R4), IL‑18 R alpha (IL-1 Rrp/IL-1 R5), IL-1 Rrp2 (IL-1 RL2/IL-1 R6), IL‑18 R beta (AcPL/IL-1 R7), IL1RAPL1 (TIGIRR-2/IL-1 R8), and IL1RAPL2 (TIGIRR-1/IL-1 R9) (1). All family members possess three immunoglobulin (Ig)-like domains in their extracellular region. Most members also have an intracellular TIR (Toll-like receptor/IL-1 receptor signaling) domain that is also conserved in the Toll-like receptor family. Related proteins, SIGIRR (single Ig domain-containing IL-1 R-related molecule) and IL‑18BP, differ from the other members by having only one Ig domain (1). IL-1 receptor accessory protein-like 2 (IL-1 RAPL2) is alternately known as IL-1 R9 and three immunoglobulin domain containing IL-1 receptor-related molecule 1 (TIGIRR-1) and is expressed in the brain (2). Its sequence predicts an 686 amino acid (aa) residue type I transmembrane glycoprotein with a 17 aa signal peptide, a 339 aa extracellular region containing three Ig-like domains, an 18 aa transmembrane domain and a 312 aa cytoplasmic tail (3). By comparison to other IL-1 receptor family proteins, IL1RAPL2 has a C-terminal cytoplasmic extension beyond the TIR domain that is found in IL1RAPL1 and SIGIRR but not other family members (3). Human and mouse IL1RAPL2 share approximately 95% aa sequence identity. Human IL1RAPL2 is most homologous (63%) to IL1RAPL1, a receptor protein that is highly expressed in hippocampus and is involved in X-linked mental retardation (4, 5). Genes for both have been localized to human chromosome Xq22. A ligand for IL1RAPL2 has not been identified (1).
