1.A.56.1.1
Plasma membrane copper uptake transporter; takes up Cu2+ into the cytoplasm (Andrés-Colás et al. 2010).  Met-rich motifs in the N-terminal region, an MXXXM motif in TMS-2, and a GXXXG motif in TMS-3 could be essential for Cu transport since they are highly conserved in all analyzed species (Vatansever et al. 2016). High-affinity copper transporters in Solanum lycopersicum have been characterized (Romero et al. 2021).
