The role of copper in the early ubiquitination pathway. This project aims to explore the role of copper in ageing and protein turnover. The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system.

The removal of damaged or excess proteins is achieved by ubiquitin-tagging in all kingdoms of life. It has recently been observed that one of the earliest steps of this process appears to be driven by copper. This project aims to elaborate the precise biochemical mechanisms by which copper regulates this important tagging and protein turnover system. It proposes to characterise the structure and function of a newly identified copper-dependent form of cell enzyme which could be involved in amplifying ubiquitin-tagged protein breakdown. Copper is essential for life in all domains. Identifying copper as a major regulator in protein clearance is important in understanding this fundamental biological machinery.Read moreRead less
Detecting stress-induced changes to subcellular copper pools in brain cells. Copper (Cu) plays essential roles in the functioning of brain cells, but the regulation and activity of this metal is poorly understood. This project aims to map sub-cellular Cu pools in brain cells, with particular emphasis on the effects of cellular stresses on these pools. These studies are expected to contribute important new methods for the study of Cu biology, and could provide valuable information about how Cu ho ....Detecting stress-induced changes to subcellular copper pools in brain cells. Copper (Cu) plays essential roles in the functioning of brain cells, but the regulation and activity of this metal is poorly understood. This project aims to map sub-cellular Cu pools in brain cells, with particular emphasis on the effects of cellular stresses on these pools. These studies are expected to contribute important new methods for the study of Cu biology, and could provide valuable information about how Cu homeostasis is maintained or perturbed under various stresses. In the future, this work is expected to form the basis of studies of brain Cu pools in neurodegenerative diseases.Read moreRead less
