Small GTPases. - PubMed Central (PMC)
Small GTPases are tightly regulated molecular switches that make binary on/off decisions through controlled loading of GTP (activation) and hydrolysis of GTP to GDP (inactivation). Small GTPases typically function as nodal points that integrate broad upstream regulatory inputs and disseminate broad effector outputs.

Small GTPase - an overview | ScienceDirect Topics
Small GTPase inhibitor screening. Small GTPases are a family of cytosolic G proteins acting in many ways equally to G α proteins in the case of GPCR. Small GTPases are involved in regulation of key cellular processes, including cell division, signal transduction, and apoptosis.
