Caption: RAS protein. Computer graphic representation of a RAS protein molecule bound to GDP cofactor. The ribbon structure of the RAS protein is depicted (white) with the bound GDP cofactor (red). RAS is a cell membrane protein associated with the complex series of enzyme reactions that regulate cell growth signalling. The cofactor is a low weight, non protein molecule that is needed for ras to work. Under certain conditions ras protein can cause uncontrolled multiplication of cells, causing a cancer tumour to develop. For this reason RAS protein has been the subject of
