Summary: Enables identical protein binding activity; lipopolysaccharide binding activity; and monosaccharide binding activity. Involved in several processes, including negative regulation of interleukin-2 production; opsonization; and regulation of phagocytosis. Located in extracellular space and multivesicular body.

SPA binds dipalmitoyl-phosphatidylcholine, the major surfactant lipid component, but not phosphatidylinositol; SPD exhibits the opposite preference.

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.
