Newly made mRNAs are processed and packaged into mature ribonucleoprotein complexes (mRNPs) and are recognized by the essential transcription-export complex (TREX) for nuclear export<sup>1,2</sup>. However, the mechanisms of mRNP recognition and three-dimensional mRNP organization are poorly understood<sup>3</sup>. Here we report cryo-electron microscopy and tomography structures of reconstituted and endogenous human mRNPs bound to the 2-MDa TREX complex. We show that mRNPs are recognized throug  ...[more]
