Increased mitogen-activated protein kinase (MAPK) signaling, small GTPase activation, cytoskeletal rearrangements, and the directed targeting of proteases to sites of extracellular matrix degradation all accompany the process of tumor cell invasion. Several studies have implicated the small GTP-binding protein ARF6 in tumor cell invasion, although the molecular basis by which ARF6 facilitates this process is unclear.
