Also known as: l7R3; Saa-3
Summary: Enables Toll-like receptor 4 binding activity and chemoattractant activity. Acts upstream of or within several processes, including I-kappaB phosphorylation; cellular response to interleukin-1; and response to stilbenoid. Located in extracellular space. Is expressed in cerebellum; ileum; liver; reproductive system; and thymus. Orthologous to several human genes including SAA2 (serum amyloid A2). [provided by Alliance of Genome Resources, Apr 2022]
Expression: Biased expression in liver E18 (RPKM 11.8), genital fat pad adult (RPKM 2.2) and 8 other tissues See more

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.
