Messenger RNA (mRNA) maturation is a crucial step in gene expression, requiring the coordinated action of multiple cellular machines. These machines make dramatic changes to the mRNA, the mRNA-bound proteins, and ultimately prepare mature mRNA for export from nucleus to cytoplasm. We apply structural and functional methods to reveal the molecular basis of human mRNA biogenesis and the coordination between maturation events. Our goal is to understand how an mRNA is made.
