Also known as: Lcn13; Obp2b
Summary: Predicted to enable odorant binding activity. Predicted to act upstream of or within several processes, including insulin receptor signaling pathway; negative regulation of gluconeogenesis; and regulation of lipid metabolic process. Predicted to be active in extracellular space. Orthologous to human OBP2A (odorant binding protein 2A) and OBP2B (odorant binding protein 2B). [provided by Alliance of Genome Resources, Dec 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.
