Regulation of gene expression - Take off your cap!

Through use of the PROXIMA-1 and PROXIMA-2A beamlines, researchers of the Ecole Polytechnique (CNRS, Palaiseau) and IGBMC (CNRS, INSERM and Strasbourg University) have determined the structure of a complex of proteins: the enzyme Dcp2, associated with its two 'helper molecules', the cofactors Dcp1 and Edc3. The structure of this complex has revealed the mechanism of action of...
