Summary: Enables iron-responsive element binding activity. Acts upstream of or within several processes, including intestinal absorption; osteoclast differentiation; and protoporphyrinogen IX biosynthetic process. Located in cytosol. Is expressed in several structures, including nervous system and yolk sac. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human IREB2 (iron responsive element binding protein 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.
