Hepatitis C virus (HCV) proteins are key to understanding its life cycle and developing new antiviral drugs. Research has advanced significantly due to heterologous expression and replicon systems, aiding drug development.

Area of Science:

  • Virology
  • Molecular Biology
  • Biochemistry

Background:

  • Hepatitis C virus (HCV) encodes a polyprotein processed into 10 polypeptides.
  • An overlapping +1 reading frame may produce an additional HCV protein.
  • HCV research was limited by the absence of a productive cell culture system.

Purpose of the Study:

  • To review current knowledge on the functions and biochemical features of HCV proteins.
  • To provide a framework for understanding HCV molecular mechanisms and life cycle.
  • To highlight the role of HCV protein knowledge in antiviral drug development.

Main Methods:

  • Utilizing data from heterologous expression systems for HCV proteins.
  • Employing replicon systems for functional studies.
