What is gtpase

The Arf subfamily is involved in vesicle transport and membrane trafficking. Additionally, guanine dissociation inhibitors GDIs can bind to small GTPases and regulate their location in the membrane or cytoplasm. To learn more about our GDPR policies click here.

These are small monomeric proteins homologous to Ras. They are also called small GTPases. Small GTPases have a molecular weight of about 21 kilo-Dalton and generally serve as molecular switches for a variety of cellular signaling events. According to their primary amino acid sequences and biochemical properties, the Ras superfamily is further divided into five subfamilies: Ras , Rho , Rab , Arf and Ran.

These GTPases play an important role in initiation, elongation and termination of protein biosynthesis. See dynamin as a prototype for large GTPases. Categories: Signal transduction EC 3.
