High affinity iron permease; part of the reductive iron assimilatory system (RIA), a siderophore-independent high affinity iron uptake mechanism (PubMed:15504822). Expression is up-regulated during iron starvation and is controlled by the GATA-type transcription factor sreA and the Zinc cluster transcription factor acuM (PubMed:15504822, PubMed:18721228, PubMed:21062375). Does not affect the virulence in a murine model of invasive aspergillosis (PubMed:15504822). Displays an 8-fold increase in external siderophore triacetylfusarinine C (TAFC) production after 12h of growth in iron-depleted conditions (PubMed:15504822). Belongs to the oxidase-dependent Fe transporter (OFeT) (TC 9.A.10.1) family.
