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

Aconitase 1 (ACO1), also known as cytoplasmic aconitate hydratase and iron regulatory protein 1 (IRP1), is a bifunctional human protein linking citrate metabolism with iron-responsive post-transcriptional regulation.
Biological function: ACO1 is a bifunctional cytosolic protein. When assembled with a [4Fe-4S] cluster it acts as aconitase, catalysing the reversible interconversion of citrate and isocitrate through cis-aconitate. Under iron-limiting conditions, loss of the cluster enables ACO1/IRP1 to bind iron-responsive elements in target mRNAs and regulate proteins involved in cellular iron uptake, storage and use.
