Protein
Metallothionein-like protein 3
Organism
Arabidopsis thaliana
Function
Metallothioneins have a high content of cysteine residues that bind various heavy metals (Probable). Functions as metal chelator of copper (Cu) and zinc (Zn) (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).
Similarity
Belongs to the metallothionein superfamily. Type 15 family.
