-   Size: 61 amino acids
-   Molecular mass: 6120 Da
-   Protein Accession: P04731 (Human)
-   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.
-   Family: Belongs to the metallothionein superfamily. Type 1 family. [[https://www.genecards.org/cgi-bin/carddisp.pl?gene=MT1A&keywords=MT1A#proteins-structures](https://www.genecards.org/cgi-bin/carddisp.pl?gene=MT1A&keywords=MT1A#proteins-structures)]
