Toll-like receptor 1 (TLR1) is a member of Toll-like receptors (TLRs), which is a family of pattern recognition receptors (PRRs) that form the cornerstone of the innate immune system. TLR1 recognizes bacterial lipoproteins and glycolipids in complex with TLR2. TLR1 is a cell surface receptor. TLR1 is in humans encoded by the TLR1 gene, which is located on chromosome 4.
