Summarize the biochemical mechanisms through which Rho family small GTPases regulate actin cytoskeleton dynamics and coordinate essential cellular processes.
Synthesized biochemical and cellular evidence describing the signaling pathways of small guanosine triphosphatases.
Analyzed downstream effector interactions mediating actin filament remodeling, motility, and cell architecture across eukaryotic model systems.
Rho family small GTPases function as molecular switches that govern actin assembly, establishing cell shape, polarity, and division.
Effector target interactions link Rho GTPase activation to broader physiological functions, including cell adhesion and gene transcription pathways.
