General annotation (Comments)
| Function | Metallothioneins have a high content of cysteine residues that bind various heavy metals By similarity. |
| Domain | Class I metallothioneins contain 2 metal-binding domains: four divalent ions are chelated within cluster A of the alpha domain and are coordinated via cysteinyl thiolate bridges to 11 cysteine ligands. Cluster B, the corresponding region within the beta domain, can ligate three divalent ions to 9 cysteines. |
| Sequence similarities | Belongs to the metallothionein superfamily. Type 1 family. |
