As per its classification, Ras has an intrinsic GTPase activity, which means that the protein on its own will hydrolyze a bound GTP molecule into GDP.

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 ].
WebRho GTPases are essential regulators of the actin cytoskeleton. They are involved in various physiological and biochemical processes such as the regulation of cytoskeleton dynamics, development, proliferation, survival, and regeneration. WebGTPase biosensors, like KARs, are based off of a modular design composed of a molecular switch and a FRET pair. When GTP binds to Ras, it induces a conformational change in the effector region of Ras and consequently recruits and activates downstream molecules, including the serine/threonine kinase Raf.
WebMar 23, 2024 · Wiskott-Aldrich Syndrome (WAS) family proteins are downstream effectors of Rho family GTPases that usually function in a one-to-one correspondence to regulate branched actin nucleation. In particular, the WAS protein Scar/WAVE has been shown to exhibit one-to-one correspondence with Rac GTPase.
