Function

[MT2_RAT] Metallothioneins have a high content of cysteine residues that bind various heavy metals; these proteins are transcriptionally regulated by both heavy metals and glucocorticoids.

Publication Abstract from PubMed

Metallothioneins are small cysteine-rich proteins capable of binding heavy metal ions such as Zn2+ and Cd2+. They are ubiquitous tissue components in higher organisms, which tentatively have been attributed both unspecific protective functions against toxic metal ions and highly specific roles in fundamental zinc-regulated cellular processes. In this paper a detailed comparison of the NMR solution structure [Schultze, P., Worgotter, E., Braun, W., Wagner, G., Vasak, M., Kagi, J. H. R. & Wuthrich, K. (1988) J. Mol. Biol. 203, 251-268] and a recent x-ray crystal structure [Robbins, A. H., McRee, D. E., Williamson, M., Collett, S. A., Xoung, N. H., Furey, W. F., Wang, B. C. & Stout, C. D. (1991) J. Mol. Biol. 221, 1269-1293] of rat metallothionein-2 shows that the metallothionein structures in crystals and in solution have identical molecular architectures. The structures obtained with both techniques now present a reliable basis for discussions on structure-function correlations in this class of metalloproteins.
