FPN3 — Daucus carota subsp. sativus

Summary

DCAR_005423, also known as DcFPN3, encodes a ferroportin-1 family protein with iron channel activity and transmembrane transporter activity. This carrot gene on chromosome 2 is associated with iron ion membrane transport, cellular iron ion homeostasis, and iron transport, and has been linked to iron homeostasis and decreased responses to hypoxia, heat, and oxidative stress. The protein localises to the chloroplast envelope, membrane, mitochondria, and plasmalemma. Related genes in other species link the family to iron transport and stress responses, though these associations are not yet established in carrot.
