Predicted to enable interleukin-1 receptor binding activity and signaling receptor activity. Predicted to be involved in several processes, including positive regulation of interleukin-8 production; positive regulation of nitric oxide biosynthetic process; and positive regulation of toll-like receptor signaling pathway. Predicted to act upstream of or within innate immune response. Predicted to be located in membrane. Predicted to be integral component of plasma membrane. Is expressed in brain; olfactory epithelium; spinal cord; and trunk unsegmented mesenchyme. Human ortholog(s) of this gene implicated in Legionnaires' disease; cystic fibrosis; cystitis; melioidosis; and systemic lupus erythematosus. Orthologous to human TLR5 (toll like receptor 5).
