Expression -- Description ? help Back to Top
Source Description
UniprotTISSUE SPECIFICITY: Expressed in roots and inflorescence, and to a lower extent, in leaves and stems. In roots, confined to the outer cell layers, specifically in the differentiation zone. Also detected in the endodermis and inner tissues of the central cylinder. {ECO:0000269|PubMed:12679534, ECO:0000269|PubMed:15539473, ECO:0000269|PubMed:15556641}.
Functional Description ? help Back to Top
Source Description
UniProtTranscription factor. Essential protein involved in iron uptake responses. Regulates FRO2 at the level of mRNA accumulation and IRT1 at the level of protein accumulation. Confers enhanced iron mobilization responses at low iron supply. {ECO:0000269|PubMed:15539473, ECO:0000269|PubMed:15556641, ECO:0000269|PubMed:16117851}.
