Mammalian mRNA biogenesis is dependent on specific recognition of a hexanucleotide AAUAAA motif in the polyadenylation signals (PAS) of pre-mRNA transcripts by the cleavage and polyadenylation specificity factor (CPSF) complex. Here we report a 3.1 Å resolution cryo-electron microscopy structure of a core CPSF module bound to the PAS hexamer motif. The structure reveals molecular interactions responsible for base-specific recognition, providing a rationale for mechanistic differences between mammalian and yeast 3’ polyadenylation.
