Detects mouse TLR1 in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 30% cross-reactivity with recombinant mouse (rm) TLR6 is observed, 5% cross-reactivity with recombinant human (rh) TLR1 and rmTLR2 is observed, and less than 2% cross-reactivity with rhTLR3 and rhTLR4 is observed.

The Toll-like family of molecules are type I transmembrane proteins that serve as pattern recognition receptors for microbial pathogens. There are at least twelve mouse and ten human TLRs that activate the innate immune system following exposure to a variety of microbial species (1, 2). TLRs contain a large number of leucine-rich repeats (LRRs) and a cytoplasmic tail with one Toll/IL-1 receptor (TIR) domain. Mature mouse TLR1 consists of a 557 amino acid (aa) extracellular domain (ECD) with 20 LRRs, a 21 aa transmembrane segment, and a 192 aa cytoplasmic domain (3, 4). Within the ECD, mouse TLR1 shares 60% aa sequence identity with mouse TLR6 and 19%‑27% aa sequence identitity with mouse TLR2, -3, -4, -5, -7, -8, -9, -11, -12, and -13. It shares 73% and 86% aa sequence identity with human and rat TLR1, respectively. TLR1 is expressed on the surface of macrophages, dendritic cells, and tonsillar epithelial cells in ligand-independent association with TLR2 (5‑8). TLR2 additionally associates with TLR6 to form a functional complex with specificity for distinct but related microbial ligands (9‑11). TLR1 and TLR2 cooperate in the recognition of bacterial and protozoal triacylated lipopeptides and glycosylphosphatidylinositols (6, 10‑12). Ligand binding induces TLR1 localization to lipid rafts followed by receptor internalization and activation of NF kappa B (7, 11, 13).
