image: Knowing when and where a given signaling protein is activated within intact animals permits elucidating its functions. The activation patters of Cdc42 guanosine triphosphatase (GTPase) in neurons in the brain are visualized using genetically encoded molecular bioprobe in living Drosophila embryos. This image relates to an article that appeared in the June 5, 2009, issue of Science, published by AAAS. The study, by Dr. D. Kamiyama at the University of Miami in Coral Gables, FL and colleagues, was titled, "Endogenous Activation Patterns of Cdc42 GTPase Within Drosophila Embryos." view more
