CC -!- FUNCTION: METALLOTHIONEINS HAVE A HIGH CONTENT OF CYSTEINE CC RESIDUES THAT BIND VARIOUS HEAVY METALS; THESE PROTEINS ARE CC TRANSCRIPTIONALLY REGULATED BY BOTH HEAVY METALS AND CC GLUCOCORTICOIDS. CC -!- CLASS I METALLOTHIONEINS CONTAIN 2 METAL-BINDING DOMAINS: FOUR CC DIVALENT IONS ARE CHELATED WITHIN CLUSTER A OF THE ALPHA DOMAIN CC AND ARE COORDINATED VIA CYSTEINYL THIOLATE BRIDGES TO 11 CYSTEINE CC LIGANDS. CLUSTER B, THE CORRESPONDING REGION WITHIN THE BETA CC DOMAIN, CAN LIGATE THREE DIVALENT IONS TO 9 CYSTEINES.
