The Effector Interactions of p21ras

Trends Biochem Sci. 1993 Jul;18(7):250-4. doi: 10.1016/0968-0004(93)90175-m.


Genetic, physical and biochemical methods have been used successfully to identify discrete regions of the p21ras protein involved in protein-protein interactions. Of special interest are the effector residues of p21ras, which are essential for downstream signalling. This review details current understanding of what these residues are and how they bind and activate proteins essential to the ras pathway.
