Understanding nuclear mRNA export: Survival under stress
Nuclear messenger RNA (mRNA) export is vital for cell survival under both physiological and stress conditions. To cope with stress, cells block bulk mRNA export while selectively exporting stress-specific mRNAs. Under physiological conditions, nuclear adaptor proteins recruit the mRNA exporter to the mRNA for export. By contrast, during stress conditions, the mRNA exporter is likely directly recruited to stress-specific mRNAs at their transcription sites to facilitate selective mRNA export. In this review, we summarize our current understanding of nuclear mRNA export. Importantly, we explore insights into the mechanisms that block bulk mRNA export and facilitate transcript-specific mRNA export under stress, highlighting the gaps that still need to be filled.
