GATA-type transcription repressor that regulates iron- acquisition genes through specific binding GATA sequence elements of target promoters (PubMed:9988696, PubMed:11555288). Iron acquisition regulation is critical for survival under both iron-limiting conditions (to acquire essential iron) and iron-replete conditions (to limit iron toxicity) (PubMed:11555288). SreA targets include genes encoding a number of key iron-regulated factors such as those involved in siderophore biosynthesis (PubMed:11555288, PubMed:12196195, PubMed:12487628). Expression is induced in mycelia grown in high iron medium or transferred from low iron medium into high iron medium, and repressed in mycelia grown in low iron medium or transferred from high iron medium into low iron medium (PubMed:9988696). The conserved cystein-rich region (CRR) localized between the zinc fingers is also involved in DNA-binding and transcription repressor activity (By similarity). Leads to increased iron uptake (PubMed:9988696). leads to partial derepression of triacetylfusarinine C (TAFC) and fusigen production as well as to cellular accumulation of ferricrocin (FC) (PubMed:11555288). Leads also to increased oxidative stress (PubMed:11555288).
