Summary: Enables 3 iron, 4 sulfur cluster binding activity; 4 iron, 4 sulfur cluster binding activity; and aconitate hydratase activity. Involved in several processes, including response to isolation stress; tricarboxylic acid cycle; and tricarboxylic acid metabolic process. Predicted to be active in cytosol and mitochondrial matrix. Human ortholog(s) of this gene implicated in infantile cerebellar-retinal degeneration and optic atrophy 9. Orthologous to human ACO2 (aconitase 2).

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.
