Regulation of mRNP dynamics along the export pathway.
The transcription of mRNA is tightly coupled to the concomitant recruitment of mRNA processing and export factors, resulting in the formation of mature and export competent mRNP complexes. This interconnection in gene expression implies extensive spatio-temporal control of mRNP dynamics to prevent mRNA export factors bound to pre-mRNA from functioning at the incorrect time and exporting nascent or incompletely processed pre-mRNAs. Recent discoveries provide molecular understanding of how a broad range of post-translational modifications together with RNA-dependent ATPases coordinate proteins acting at different steps and regulate mRNP assembly and export.
