Ras and Rho GTPases A Family Reunion
Rap1, is required to define the position of the new bud. 1997). In vitro, this interaction is not sufficient to stimulate the GEF activity of Cdc24p, and one functional out-and Molecular Biology University College London come of this interaction in vivo, therefore, is likely to be the localization of Cdc24p to the presumptive bud site London WC1E 6BT United Kingdom (Zheng et al., 1995). In S. p...
متن کاملRho and Ras GTPases in axon growth, guidance, and branching.
The establishment of precise neuronal cell morphology provides the foundation for all aspects of neurobiology. During development, axons emerge from cell bodies after an initial polarization stage, elongate, and navigate towards target regions guided by a range of environmental cues. The Rho and Ras families of small GTPases have emerged as critical players at all stages of axonogenesis. Their ...
متن کاملRho and Ras GTPases in semaphorin-mediated neuronal development
Neurons are highly polarized cells with a single long axon and multiple dendrites, all of which are actinrich structures. The precise regulation of neuronal cell morphology is a fundamental aspect of neurobiology. The major role of Rho GTPases, which is conserved in all eukaryotes, is to regulate the actin and microtubule cytoskeleton. Therefore the Rho GTPases are key regulators of neuronal mo...
متن کاملRho GTPases: regulation of cell polarity and growth in yeasts.
Eukaryotic cells display a wide range of morphologies important for cellular function and development. A particular cell shape is made via the generation of asymmetry in the organization of cytoskeletal elements, usually leading to actin localization at sites of growth. The Rho family of GTPases is present in all eukaryotic cells, from yeast to mammals, and their role as key regulators in the s...
متن کاملRho GTPases
Cell migration is a complex, dynamic process that involves continuous remodeling of the cellular architecture, which is needed in order for the cell to move and adapt to changes in the surrounding environment. It requires rapidly activated and spatiotemporally regulated signaling networks that enable cellular responses to external cues. Rho-family GTPases are key components of these signaling n...
