Guanylate-binding proteins (GBPs) form a family of dynamin-related large GTPases which mediate important innate immune functions. They were proposed to form oligomers upon GTP binding/hydrolysis, but ...

Although there are more than 150 guanosine triphosphate (GTP)–binding proteins, or GTPases, only the GTPase KRas G12C has proved susceptible to small-molecule drugs. That’s because it’s tough to find ...

RHOJ, a small GTPase, could hold the key to the survival of tumor cells during cancer treatments. When epithelial cells transformed into mesenchymal cells, the Rho-related GTP-binding protein RhoJ ...
