Coordinating mRNA maturation: The U1 relay model. [PDF]
Mol CellmRNA maturation requires precise coordination among transcription, 5' capping, splicing, and 3' end formation. Recent biochemical, structural, and genomic studies demonstrate that these processes are tightly coupled through dynamic interactions among RNA polymerase II, the spliceosome, and cleavage-polyadenylation complexes. Here, we synthesize current
