UniProt Comments
Metallothioneins have a high content of cysteine residues that bind various heavy metals (Probable). Functions as metal chelator of copper (Cu) and zinc (Zn). Plays a role in Cu homeostasis in the roots under elevated Cu concentration. Functions cooperatively with the phytochelatin synthase PCS1 to protect plants from Cu and cadmium (Cd) toxicity (PubMed:18287486). Plays a role in Cu homeostasis, specifically in the remobilization of Cu from senescing leaves. The mobilization of Cu from internal sources is important for seed development (PubMed:24635746). Confers tolerance to Cd and plays a role in Cd and Zn homeostasis (PubMed:16240177).
