IRT1

Functionⁱ

High-affinity iron transporter that plays a key role in the uptake of iron from the rhizosphere across the plasma membrane in the root epidermal layer. Acts as the principal regulator of iron homeostasis in planta. Also mediates the heavy metals uptake under iron-deficiency by its ability to transport cobalt, cadmium, manganese and/or zinc ions.1 Publication

Miscellaneous

Inhibited by cadmium and Fe²⁺ ions and at 100-fold excess inhibited by cobalt, manganese and zinc ions.

The availability of secondary non-iron metal substrates (Zn, Mn, and Co) controls the localization of IRT1 between the outer polar domain of the plasma membrane and early endosome/trans-Golgi network in root epidermal cells.1 Publication
