How the essential pre-mRNA splicing factor U2AF(65) recognizes the polypyrimidine (Py) signals of the major class of 3' splice sites in human gene transcripts remains incompletely understood. We determined four structures of an extended U2AF(65)-RNA-binding domain bound to Py-tract oligonucleotides at resolutions between 2 ...
