Article Synopsis
  • Influenza A viruses contain eight genomic RNAs that are transcribed in the host cell nucleus, with two undergoing alternative splicing to produce M1 and M2 mRNAs.
  • The NS1-BP protein helps facilitate the splicing of M1 to M2 mRNA by competing with the viral NS1 protein, which normally inhibits mRNA export.
  • The research suggests a mechanism where spliced M mRNAs are exported from the nucleus despite NS1's inhibitory effects, crucial for the production of viral proteins needed for replication and virus release.

In eukaryotes, RNAs transcribed by RNA Pol II are modified at the 5' end with a 7-methylguanosine (mG) cap, which is recognized by the nuclear cap binding complex (CBC). The CBC plays multiple important roles in mRNA metabolism, including transcription, splicing, polyadenylation, and export. It promotes mRNA export through direct interaction with a key mRNA export factor, ALYREF, which in turn links the TRanscription and EXport (TREX) complex to the 5' end of mRNA.

mRNA in eukaryotic cells is packaged into highly compacted ribonucleoprotein particles (mRNPs) in the nucleus and exported to the cytoplasm for translation. mRNP packaging and export require the evolutionarily conserved transcription-export (TREX) complex. TREX facilitates loading of various RNA-binding proteins on mRNA through the action of its DDX39B subunit.
