Live show of Rho GTPases in cell migration.
Rho GTPases, including RhoA, Rac1 and Cdc42, are key regulators of cell migration in animals. In a recent issue of Nature, two papers present delicate studies on precise roles and spatiotemporal coordination of Rho GTPases in live cells, using either a photoactivatable Rac1 or specific biosensors, together with computational multiplexing method. In addition to implications in cell migration, an...
متن کاملCell migration: Rho GTPases lead the way.
Rho GTPases control signal transduction pathways that link cell surface receptors to a variety of intracellular responses. They are best known as regulators of the actin cytoskeleton, but in addition they control cell polarity, gene expression, microtubule dynamics and vesicular trafficking. Through these diverse functions, Rho GTPases influence many aspects of cell behavior. This review will f...
متن کاملTargeting Rho-GTPases in immune cell migration and inflammation
UNLABELLED Leukocytes are unmatched migrators capable of traversing barriers and tissues of remarkably varied structural composition. An effective immune response relies on the ability of its constituent cells to infiltrate target sites. Yet, unwarranted mobilization of immune cells can lead to inflammatory diseases and tissue damage ranging in severity from mild to life-threatening. The effica...
متن کاملRho GTPases in hematopoietic stem/progenitor cell migration.
Rho GTPases including RhoA, Rac1, and Cdc42 are a class of intracellular signaling proteins critical for the regulation of cytoskeleton organization, adhesion, and migration. Molecular mechanisms of mammalian cell migration were first revealed in fibroblasts where RhoA, Rac1, and Cdc42 facilitate in the multistep process including establishment and maintenance of polarity, formation of actin-ri...
متن کاملDifferential Localization of Rho Gtpases in Live Cells
Determinants of membrane targeting of Rho proteins were investigated in live cells with green fluorescent fusion proteins expressed with or without Rho-guanine nucleotide dissociation inhibitor (GDI)alpha. The hypervariable region determined to which membrane compartment each protein was targeted. Targeting was regulated by binding to RhoGDI alpha in the case of RhoA, Rac1, Rac2, and Cdc42hs bu...
