Messenger RNA (mRNA) export from the nucleus requires coordinated processing into messenger ribonucleoprotein complexes (mRNPs). This review summarizes yeast and mammalian factors involved in mRNA export through nuclear pore complexes (NPCs).

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Background:

  • Messenger RNA (mRNA) export from the nucleus is a critical step in gene expression.
  • This process involves the formation of export-competent messenger ribonucleoprotein complexes (mRNPs).
  • Numerous factors facilitate mRNA translocation through nuclear pore complexes (NPCs).

Purpose of the Study:

  • To summarize recent advancements in understanding mRNA export mechanisms.
  • To review the characterization of factors involved in yeast and mammalian mRNA export.
  • To highlight the importance of functional characterization and interaction networks.

Main Methods:

  • Genetic approaches in yeast to identify export factors.
  • Identification of functional homologues in metazoan systems.
