Summary: Enables fibronectin binding activity; integrin binding activity; and protein phosphatase binding activity. Involved in negative regulation of immunoglobulin production and negative regulation of leukocyte activation. Acts upstream of or within several processes, including alpha-beta T cell proliferation; cellular response to lipopolysaccharide; and response to nematode. Located in external side of plasma membrane. Is expressed in urinary system. Orthologous to human LILRB4 (leukocyte immunoglobulin like receptor B4).

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.
