Ras proteins are monomeric GTPases that act as binary molecular switches to regulate a wide range of cellular processes. The exchange of GTP for GDP on Ras is regulated by guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs), which regulate the activation state of Ras without covalently modifying it. In contrast, post-translational modifications (PTMs) of Ras proteins direct them to various cellular membranes and, in some cases, modulate GTP–GDP exchange. Important Ras PTMs include the constitutive and irreversible remodelling of its C-terminal CAAX motif by farnesylation, proteolysis and methylation, reversible palmitoylation, and conditional modifications including phosphorylation, peptidyl-proly isomerisation, mono- and di-ubiquitination, nitrosylation, ADP ribosylation and glucosylation.
