One of the open questions in RAS biology is the existence of RAS dimers and their role in RAF dimerization and activation. The idea of RAS dimers arose from the discovery that RAF kinases function as obligate dimers, which generated the hypothesis that RAF dimer formation might be nucleated by G-domain-mediated RAS dimerization. Here, we review the evidence for RAS dimerization and describe a recent discussion among RAS researchers that led to a consensus that the clustering of two or more RAS proteins is not due to the stable association of G-domains but, instead, is a consequence of RAS C-terminal membrane anchors and the membrane phospholipids with which they interact.
