6B3X - PubMed Abstract: 
Cleavage stimulation factor (CstF) is a highly conserved protein complex composed of three subunits that recognizes G/U-rich sequences downstream of the polyadenylation signal of eukaryotic mRNAs. While CstF has been identified over 25 years ago, the architecture and contribution of each subunit to RNA recognition have not been fully understood ...
