Summary: Enables iron-responsive element binding activity. Involved in osteoclast differentiation. Acts upstream of or within several processes, including erythrocyte homeostasis; multicellular organismal-level iron ion homeostasis; and protoporphyrinogen IX biosynthetic process. Located in cytosol. Is expressed in several structures, including genitourinary system; hemolymphoid system gland; liver; 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 2025]
Expression: Broad expression in CNS E11.5 (RPKM 14.9), CNS E14 (RPKM 13.7) and 23 other tissues See more

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.
