CC -!- FUNCTION: Metallothioneins have a high content of cysteine residues
CC that bind various heavy metals; these proteins are transcriptionally
CC regulated by both heavy metals and glucocorticoids.
CC -!- DOMAIN: Class I metallothioneins contain 2 metal-binding domains: four
CC divalent ions are chelated within cluster A of the alpha domain and are
CC coordinated via cysteinyl thiolate bridges to 11 cysteine ligands.
CC Cluster B, the corresponding region within the beta domain, can ligate
CC three divalent ions to 9 cysteines.
CC -!- SIMILARITY: Belongs to the metallothionein superfamily. Type 1 family.
CC {ECO:0000305}.
