RNA localization, the spatial regulation of RNA molecules, is crucial for cell polarity. This review details its functions and mechanisms, using Ash1 mRNA and retroviral RNAs as examples.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Genetics

Context:

  • RNA localization is a conserved biological process.
  • Over 100 RNAs are known to be spatially regulated.
  • RNA localization plays a key role in establishing cell polarity.

Purpose:

  • To review the diverse functions of RNA localization.
  • To elucidate the detailed mechanisms of RNA localization.
  • To provide insights into the spatial regulation of gene expression.

Summary:

  • RNA localization directs gene expression to specific subcellular locations.
  • It influences cell polarity by interpreting spatial cues or controlling cytoskeletal organization.
  • Mechanisms are explored through examples like Ash1 mRNA in yeast and retroviral RNAs in mammals.
