Sensing coiled-coil proteins through conformational modulation of energy transfer processes – selective detection of the oncogenic transcription factor c-Jun

Author affiliations

Abstract

Designed terbium-chelating peptides were used to monitor the formation of leucine zipper associations. The sensing strategy is based on the modulation of the antenna effect from a Trp residue donor and the luminescence increase arising from the folding that takes place upon the formation of the coiled-coil structure. An application in the specific sensing of the oncogenic c-Jun transcription factor is demonstrated.
