5. filopodium Rho Family Small G Proteins Play Central Roles in Cell Motility and Invasiness Rac, Cdc42, Rho and their GEFs (eg Tiam1 Rac) are all involved in the orchestration of extension/sensing/contraction and MMP secretion that are involved in the movement of cells across surfaces. A role for Rho proteins is demonstrated by studies of melanoma.
