Predicted to enable lipopolysaccharide immune receptor activity. Involved in lipopolysaccharide-mediated signaling pathway; positive regulation of tumor necrosis factor production; and toll-like receptor 4 signaling pathway. Acts upstream of or within positive regulation of lipopolysaccharide-mediated signaling pathway. Part of lipopolysaccharide receptor complex. Is expressed in several structures, including extraembryonic component; gonad; immune system; integumental system; and nervous system. Orthologous to human LY96 (lymphocyte antigen 96).
