Small ARF-like 2 GTPase TITAN 5 is linked with the dynamic regulation of IRON-REGULATED TRANSPORTER 1

bioRxiv
Iron acquisition is crucial for plants. The abundance of IRON-REGULATED TRANSPORTER 1 (IRT1) at the plasma membrane is controlled through endomembrane trafficking. Vesicular trafficking requires small ARF-like GTPases, one of them is TITAN 5 (TTN5).
