Summary: Enables lipopolysaccharide binding activity and signaling receptor binding activity. Involved in several processes, including macrophage activation involved in immune response; positive regulation of metabolic process; and response to bacterium. Acts upstream of or within leukocyte chemotaxis involved in inflammatory response; positive regulation of chemokine production; and positive regulation of neutrophil chemotaxis. Located in cell surface and extracellular space. Is expressed in brain; heart ventricle; liver lobe; and reproductive system. Orthologous to human LBP (lipopolysaccharide binding protein).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
