Abstract

It is now established that the function of many signaling molecules is controlled, in part, by regulation of subcellular localization. For example, the dynamic recruitment of normally cytosolic proteins to the plasma membrane, by activated Ras or activated receptor tyrosine kinases, facilitates their interaction with other membrane-associated components that participate in their full activation (e.g., Raf-1). Therefore, the creation of chimeric proteins that contain lipid-modified signaling sequences that direct membrane localization allows the generation of constitutively activated variants of such proteins. The amino-terminal myristoylation signal sequence of Src family proteins and the carboxy-terminal prenylation signal sequence of Ras proteins have been widely used to achieve this goal. Such membrane-targeted variants have proved to be valuable reagents in the study of the biochemical and biological properties of many signaling molecules.
