Citation | Journal: Proc Natl Acad Sci U S A / Year: 2018 Title: Molecular basis for the recognition of the human AAUAAA polyadenylation signal. Authors: Yadong Sun / Yixiao Zhang / Keith Hamilton / James L Manley / Yongsheng Shi / Thomas Walz / Liang Tong / Abstract: Nearly all eukaryotic messenger RNA precursors must undergo cleavage and polyadenylation at their 3'-end for maturation. A crucial step in this process is the recognition of the AAUAAA ...Nearly all eukaryotic messenger RNA precursors must undergo cleavage and polyadenylation at their 3'-end for maturation. A crucial step in this process is the recognition of the AAUAAA polyadenylation signal (PAS), and the molecular mechanism of this recognition has been a long-standing problem. Here, we report the cryo-electron microscopy structure of a quaternary complex of human CPSF-160, WDR33, CPSF-30, and an AAUAAA RNA at 3.4-Å resolution. Strikingly, the AAUAAA PAS assumes an unusual conformation that allows this short motif to be bound directly by both CPSF-30 and WDR33. The A1 and A2 bases are recognized specifically by zinc finger 2 (ZF2) of CPSF-30 and the A4 and A5 bases by ZF3. Interestingly, the U3 and A6 bases form an intramolecular Hoogsteen base pair and directly contact WDR33. CPSF-160 functions as an essential scaffold and preorganizes CPSF-30 and WDR33 for high-affinity binding to AAUAAA. Our findings provide an elegant molecular explanation for how PAS sequences are recognized for mRNA 3'-end formation. | |||||||||
