Rho-proteins act as molecular switches that regulate vital processes in eucaryotic organisms. Their activation is essential for the processing of multiple internal and external stimuli. Scientists at the MPI in Dortmund recently discovered the responsible activating proteins in plants, which apparently represent the direct link to signal perceiving cell surface receptors. Although these proteins differ significantly from their analogues in animals and fungi, they still follow a general reaction mechanism.
