Summary
ACO1 (aconitase 1, HGNC:117) is a protein-coding gene on chromosome 9p21.1, encoding Cytoplasmic aconitate hydratase (P21399). Bifunctional iron sensor that switches between 2 activities depending on iron availability.
The protein encoded by this gene is a bifunctional, cytosolic protein that functions as an essential enzyme in the TCA cycle and interacts with mRNA to control the levels of iron inside cells. When cellular iron levels are high, this protein binds to a 4Fe-4S cluster and functions as an aconitase. Aconitases are iron-sulfur proteins that function to catalyze the conversion of citrate to isocitrate. When cellular iron levels are low, the protein binds to iron-responsive elements (IREs), which are stem-loop structures found in the 5’ UTR of ferritin mRNA, and in the 3’ UTR of transferrin receptor mRNA. When the protein binds to IRE, it results in repression of translation of ferritin mRNA, and inhibition of degradation of the otherwise rapidly degraded transferrin receptor mRNA. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. Alternative splicing results in multiple transcript variants

Literature-anchored findings (GeneRIF, showing 4)
- identified a Twist target, T48, which acts with G protein signaling to orchestrate shape changes in the embryo; with G protein signaling, T48 recruits adherens junctions & RhoGEF2 to sites of apical constriction, ensuring changes in cell shape (PMID:17234948)
- Both genes are expressed and required for mesoderm invagination in the fruit fly Drosophila melanogaster but do not appear during mesoderm ingression of the midge Chironomus riparius. (PMID:27685537)
- Drosophila Fog/Cta and T48 pathways have overlapping and distinct contributions to mesoderm invagination. (PMID:38536475)
- Gp48 was a flavin-dependent thymidylate synthase (ThyX) that resembled the Paramecium bursaria chlorella virus-1 ThyX enzyme in its properties. (PMID:18248423)

Function. Bifunctional iron sensor that switches between 2 activities depending on iron availability. Iron deprivation, promotes its mRNA binding activity through which it regulates the expression of genes involved in iron uptake, sequestration and utilization. Binds to iron-responsive elements (IRES) in the untranslated region of target mRNAs preventing for instance the translation of ferritin and aminolevulinic acid synthase and stabilizing the transferrin receptor mRNA. Conversely, when cellular iron levels are high, binds a 4Fe-4S cluster which precludes RNA binding activity and promotes the aconitase activity, the isomerization of citrate to isocitrate via cis-aconitate.
Subunit / interactions. Interacts (when associated with the 4Fe-4S) with FBXL5. Interacts with frataxin(81-210).
Subcellular location. Cytoplasm. Cytosol.
Cofactor. Binds 1 [4Fe-4S] cluster per subunit.
Similarity. Belongs to the aconitase/IPM isomerase family.
