Could also be capable of transporting zinc ions.ALTERNATIVE PRODUCTS:Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=O81850-1; Sequence=Displayed; Name=2; IsoId=O81850-2; Sequence=VSP_026067, VSP_026068; Note=May be due to intron retention. No experimental confirmation available;TISSUE SPECIFICITY:Expressed in the external cell layers of the root subapical zone.INDUCTION:In roots by iron starvation.SIMILARITY:Belongs to the ZIP transporter (TC 2.A.5) family."
