Description

TLR1 is a single-pass type I transmembrane glycoprotein belonging to the Toll-like receptor (TLR) family. The TLR family members play a fundamental role in pathogen recognition and activation of innate immunity. They serve as pattern recognition receptors for microbial pathogens. There are at least 11 mouse and 10 human TLR members. TLRs are highly conserved from Drosophila to humans and share structural and functional similarities. TLRs contain a large number of leucine­rich repeats (LRRs) and a cytoplasmic tail with a Toll/IL­1 receptor (TIR) domain. TLRs recognize pathogen-associated molecular patterns (PAMPs) that are expressed on infectious agents, and mediate the production of cytokines necessary for the development of effective immunity. TLR1 contains 19 LRR repeats in the extracellular region. The various TLRs exhibit different patterns of expression. TLR1 is ubiquitously expressed, and at higher levels than other TLRs. It is found on the surface of macrophages, dendritic cells, and tonsillar epithelial cells in ligand­independent association with TLR2.  TLR1 and TLR2 cooperate in the recognition of bacterial and protozoal triacylated lipopeptides and glycosylphosphatidylinositols.  

 


 

Gene Symbol: TLR1; TIL; CD281; rsc786; TIL. LPRS5; KIAA0012

 

NCBI Gene ID: 7096
