Practice question
Question
Overexpression of which GTPase in GTP-bound form modulates actin cytoskeleton?
Explanation
Rho (GTP), is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.
