Protein

Toll-like receptor 2 type-1

Gene

TLR2-1

Organism
Gallus gallus (Chicken)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Participates in the innate immune response to microbial agents. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response (By similarity). Does not respond to LPS and responds with less ability than TLR2-2 to mycoplasmal macrophage-activating lipopeptide-2kD (MALP-2).By similarity
