These small GTPases (about 21 kDa) act as molecular switches that are active when they are GTP-bound, and inactive when GTP is converted to GDP, due to their intrinsic GTPase activity (Boguski

Until recently, members of the Rho-subfamily were believed to be primarily involved in the regulation of cytoskeletal organization in response to extracellular growth factors. However, studies from numerous groups over the past few years have revealed that the Rho-GTPases play crucial roles i

Like other Ras-related proteins, Rho GTPases are thought to adopt either an active GTP-bound conformational state or an inactive GDP-bound state. Although cycling between the

This volume centers particularly on one family of cellular proteins which transmit these signals, the Rho Ras-like GTPases, and examines their role in normal cellul

However, until recently little was known about the signal transduction pathways which regulate the reorganization of the cytoskeleton and cell adhesions.
