The current model of Rho GTPase activation and signaling (A) states that Rho GTPases are geranylgeranylated for transport to the plasma membrane, where their interaction with GEFs increases their GTP loading and activation. In this model, ...
The p21 activated kinases (PAKs) Rho GTPase effectors that are emerging to play a key role in cancer therapy resistance and stemness. There are two groups of PAKs [group I PAKs (1, 2, and 3) and group II PAKs (4, 5, and 6)]. This chapter highlights the multi-faceted roles of ...

RHOGEFs bind to the GDP-bound form RHO GTPase and induce the exchange of GDP for GTP to activate RHO. Subsequently, the conformation of RHO GTPases changes, which allows them to interact with their specific effectors and triggers biological effects such as cell migration, polarity and ...
Carlo Corona, Eugenie Peze-Heidsieck‡, Michael Shelanski & Lloyd A. Greene In earlier studies, we showed that ATF4 down-regulation affects post-synaptic development and dendritic spine morphology in neurons through increased turnover of the Rho GTPase Cell Division Cycle 42 (Cdc42)...

In its active state, the GTPase interacts with cellular targets or effectors (E1–x) to generate a cellular response. Currently around eight potential targets are known for each of the three GTPases, Rho, Rac, and Cdc42, but there is no reason to believe that this list is complete. ...

Rho exhibits both GDP/GTP-binding activity and GTPase activity, and functions as a molecular switch, cycling between a GDP-bound inactive state (GDP–Rho) and a GTP-bound active state (GTP–Rho)14. The activity of Rho is cyclically regulated. Thus, in resting cells, Rho GDP dissociation in...
