At3g56240: CCH (COPPER CHAPERONE)

CCH protein belongs to a family of eukaryotic proteins that participate in intracellular copper homeostasis by delivering this metal to the secretory pathway, mainly located along the vascular bundles of senescing leaves and petioles as well as in stem sieve elements, hypothesized to have a role in copper mobilization from decaying organs towards reproductive structures, as a result of metalloprotein breakdown. The plant-specific C-terminal domain of the CCH protein forms amyloid-like fibrils in vitro.
