Summary: Enables peroxidase activity. Acts upstream of or within several processes, including embryonic liver development; exocrine pancreas development; and pronephros development. Predicted to be located in endoplasmic reticulum membrane. Predicted to be active in cytoplasm and neuron projection. Is expressed in several structures, including cardiovascular system; digestive system; gonad; head; and trigeminal placode. Human ortholog(s) of this gene implicated in several diseases, including Barrett's esophagus; artery disease (multiple); arthritis (multiple); liver disease (multiple); and lung disease (multiple). Orthologous to human PTGS2 (prostaglandin-endoperoxide synthase 2). [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.
