Summary: Predicted to enable co-receptor binding activity and transferrin receptor activity. Acts upstream of or within iron ion homeostasis. Part of HFE-transferrin receptor complex. Is expressed in liver lobe; mesonephros; and urinary system. Used to study hemochromatosis type 3. Human ortholog(s) of this gene implicated in hemochromatosis and hemochromatosis type 3. Orthologous to human TFR2 (transferrin receptor 2). [provided by Alliance of Genome Resources, Apr 2022]

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.
