    ..This suggests that Npl3p follows a distinct nuclear import pathway and that intranuclear release from its specific import receptor Mtr10p requires the cooperative action of both Ran-GTP and newly synthesized mRNA. ..

    ..Together, these data shed light onto the transformation of an exporting to a translating mRNP. ..

    ..In summary, we provide insight into how the phospho-code of the CTD directs mRNP formation and export through TREX recruitment...
