Figure 4From: Roles of Sema4D and Plexin-B1 in tumor progressionControl of cellular motility by Sema 4D-Plexin-B1 interation via the intrinsic mechanism. Decreased intrinsic GAP activity of Plexin-B1 also leads to preferential signaling through the stimulatory R-Ras and Rho-dependant pathways.Back to article page
