In the Drosophila egg, during signalling through the epidermal growth factor (EGF) receptor, a conformational switch, which is dependent on mitogen-activated protein kinase (MAPK) leads to the Cf2 transcriptio-nal repressor being targeted for proteolysis. Recent work shows that this switch is catalysed by the Drosophila homologue of Pin1, a peptidyl-prolyl isomerase.
