Summary: Enables G protein-coupled receptor binding activity. Involved in response to estradiol. Predicted to be located in extracellular space. Predicted to be part of haptoglobin-hemoglobin complex and hemoglobin complex. Human ortholog(s) of this gene implicated in Heinz body anemia; alpha thalassemia; familial erythrocytosis 7; and hemoglobin H disease. Orthologous to several human genes including HBA1 (hemoglobin subunit alpha 1). [provided by Alliance of Genome Resources, Jan 2025]

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.
