TLR 1 is a member of the Toll-like receptor family (TLR) of pattern recognition receptors of the innate immune system. TLR1 recognizes pathogen-associated molecular pattern with a specificity for gram-positive bacteria. TLR1 has also been designated as CD281 (cluster of differentiation 281).TLRs are highly conserved from Drosophila to humans and share structural and functional similarities.
