Summary: Predicted to enable several functions, including amyloid-beta binding activity; heme binding activity; and oxygen binding activity. Predicted to contribute to haptoglobin binding activity and peroxidase activity. Involved in response to stilbenoid. Acts upstream of or within erythrocyte development; in utero embryonic development; and response to bacterium. Located in myelin sheath. Part of hemoglobin complex. Is expressed in several structures, including blood vessel; early conceptus; hematopoietic system; liver; and visceral pericardium. Human ortholog(s) of this gene implicated in Heinz body anemia; alpha thalassemia; familial erythrocytosis 7; and hemoglobin H disease. Orthologous to human HBA1 (hemoglobin subunit alpha 1) and HBA2 (hemoglobin subunit alpha 2). [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.
