WebOct 19, 2024 · GTPases form a large superfamily of regulatory proteins that are capable of binding GTP and hydrolysing it into GDP [ 5 ]. Members of this superfamily have been implicated in a variety of cellular processes and represent some of the most highly conserved proteins in all of life [ 4, 6, 7 ]. WebMay 4, 2011 · Consequently, small GTPases are involved in several disease states such as cancer and metabolic disorders. 1,2 GTPases are active when bound to guanosine triphosphate (GTP) and inactive when the triphosphate is hydrolyzed to guanosine diphosphate (GDP).
