	Abstract

FOX1 encodes an iron deficiency induced ferroxidase involved in a high affinity iron uptake system. Mutagenesis analysis of the FOX1 promoter identified two separate iron-responsive elements, FeRE1 (CACACG) and FeRE2 (CACGCG), between -87 to -82 and -65 to -60, and both are needed for induced FOX1 expression under iron deficiency.
