Summary
Receptors are cell-surface molecules that enable the cell to receive chemical messages from the outside environment and transmit these signals to the inside of cell. These messages tell the cells to grow, divide or die. The Epidermal Growth Factor Receptor is linked to a variety of cell signalling pathways that are critical to the normal functioning of cells. Conversely, abberations in Epidermal Growth Factor-mediated cell signalling leads to many types of cancers.

These messages tell the cells to grow, divide or die. The Epidermal Growth Factor Receptor is linked to a variety of cell signalling pathways that are critical to the normal functioning of cells. Conversely, abberations in Epidermal Growth Factor-mediated cell signalling leads to many types of cancers. A basic understanding of how the receptor is turned off or on is essential to designing drugs that can specifically inhibit its hyperproliferative response. High resolution structures of a key part of the Epidermal Growth Factor Receptor have identified several structural forms of the receptor that are providing valuable clues as to the structural basis for receptor activation. Armed with this information and advanced microscopic imaging technology we are in the unique position to probe receptor activation in living cells. This project seeks to determine which structural form of the receptor is responsible for transmission of cellular messages and how it is impaired in cancerous cells.Read moreRead less
