    The recognition of specific signals encoded within the 3'-untranslated region of the newly transcribed mRNA triggers the assembly of a multiprotein machine that modifies its 3'-end. Hrp1 recognises one of such signals, the so-called polyadenylation enhancement element (PEE), promoting the recruitment of other polyadenylation factors in yeast. The molecular bases of this interaction are revealed here by the solution structure of a complex between Hrp1 and an oligonucleotide mimicking the PEE. Six consecutive bases (AUAUAU) are specifically recognised by two RNA-binding domains arranged in tandem. Both protein and RNA undergo significant conformational changes upon complex formation with a concomitant large surface burial of RNA bases. Key aspects of RNA specificity can be explained by the presence of intermolecular aromatic-aromatic contacts and hydrogen bonds. Altogether, the Hrp1-PEE structure represents one of the first steps towards understanding of the assembly of the cleavage and polyadenylation machinery at the atomic level.
