Ribbon model of Cd5Zn2 Rat Metallothionien.
Classical biochemistry is founded around the description and characterisation of major organic metabolic pathways. Although the role of inorganics is well established, it has not been until recently that parallel intricate trafficking pathways were identified for these essential trace elements. The majority of this fundamental work has been performed on the single cellular brewers yeast, Saccharomyces cerevisiae. This knowledge has been translated into the identification of the key genes underlying genetic disorders of metal metabolism in humans, indicating the high degree of conservation of the molecular mechanisms underlying metal metabolism in eukaryotes. My research aims to dissect the function of these pathways within a range of environmental sentinel species.
One common theme within this research has been the involvement of a family of small sulphur rich proteins, namely metallothioneins on metal metabolism (Fig. 1). We have shown that these proteins act as cytosolic metal chaperones, protecting cells from the potential harm posed by ‘free’ metal ions. We have characterised the role of metallothionein within fish species (>8 original papers), seaweeds, plants and earthworms. For the latter species, over the last 10 years we have progressed from a situation of no knowledge to understanding the complete spectrum of the involvement of metallothioneins involvement in the uptake, sequestration and exclusion of metal ions.
Regulation of Zn Homeostasis in Eukaryotes.
My present research harnesses ‘omics’ tools to characterise the pathways and regulatory networks which response to and regulate the essential metal ion Zinc and Copper (Fig. 2) and the respond to toxic heavy metals and other Xenobiotics (Fig. 3).
