Area of Science:

  • Molecular Biology
  • Genetics
  • Cell Biology

Background:

  • RNA-binding proteins (RBPs) regulate diverse RNA metabolism processes, including processing, translation, stability, localization, and transport.
  • Many RBPs interact with multiple RNA targets, exhibiting multifunctional roles.
  • Specific RBPs are crucial for coordinating RNA-related events between the nucleus and cytoplasm.

Purpose of the Study:

  • To review RNA-binding proteins involved in RNA transport and localization.
  • To highlight RBPs that also participate in other RNA metabolism aspects.
  • To elucidate the role of these proteins in linking nuclear events (e.g., splicing) to cytoplasmic RNA localization.

Main Methods:

  • Literature review of studies on RNA-binding proteins.
