Summary: Predicted to enable several functions, including cation binding activity; cholesterol transfer activity; and phosphatidylcholine-sterol O-acyltransferase activator activity. Involved in innate immune response in mucosa and response to stilbenoid. Acts upstream of or within regulation of intestinal cholesterol absorption. Located in extracellular space. Is expressed in embryo and liver. Human ortholog(s) of this gene implicated in Alzheimer's disease; colitis; myocardial infarction; and ulcerative colitis. Orthologous to human APOA4 (apolipoprotein A4). [provided by Alliance of Genome Resources, Nov 2024]

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.
