Abstract
Maturation of snRNAs, key parts of the spliceosome, involves nuclear export of newly synthesized snRNAs to the cytoplasm. PHAX is known to mediate snRNA export in a phosphorylation-dependent manner, but the underlying mechanism remains elusive. A cryo-EM structure of a PHAX-containing snRNA export complex now provides insights into the pathway.
