3K8Y, 3K9N, 3LBH, 3LBI, 3LBN - PubMed Abstract: 
Ras and its effector Raf are key mediators of the Ras/Raf/MEK/ERK signal transduction pathway. Mutants of residue Q61 impair the GTPase activity of Ras and are found prominently in human cancers. Yet the mechanism through which Q61 contributes to cat ...
