The GTPase domain is a functional region found in a variety of proteins. It is involved in the hydrolysis of guanosine triphosphate (GTP) to guanosine diphosphate (GDP). This domain is crucial for the protein's role in cellular processes such as signal transduction, protein synthesis, and cell division. The GTPase domain acts as a molecular switch, toggling between active and inactive states depending on whether GTP or GDP is bound.
