- COPT4 interacts with COPT1 or COPT3 to manipulate copper-triggered immunity (CuTI) in Arabidopsis.
- Among COPT1 to COPT6, only COPT4 mutation attenuates Cu+-mediated immune responses, despite COPT4 not transporting Cu+ alone.
- COPT4 forms heterodimers with COPT1 and COPT3, which are crucial for CuTI.
- The Arabidopsis homolog of anti-oxidant 1 (ATX1) interacts with COPT1 and COPT3 but not COPT4, playing a role in CuTI.
- The bHLH107-ACS8 module is activated inside plant cells as part of the Cu+-responsive signaling pathway.
