Dual Roles of Host Zinc Finger Proteins in Viral RNA Regulation: Decay or Stabilization

Area of Science:

• Virology
• Molecular Biology
• Immunology

Background:

• Host defense mechanisms against viral infections are critical for understanding viral diseases.
• Host RNA-binding proteins (RBPs) are increasingly recognized for their roles in controlling viral replication.
• RBPs can either restrict viral infections or promote viral persistence through interactions with cofactors.

Purpose of the Study:

• To identify host proteins that regulate viral RNA, targeting viral components without harming host cells.
• To review the dual roles of RNA-binding zinc finger proteins (ZNFPs) in viral RNA regulation.
• To explore the therapeutic potential of ZNFPs in developing novel antiviral strategies.

Main Methods:

• Literature review focusing on host RNA-binding proteins and their interaction with viral RNA.
• Classification of RNA-binding zinc finger proteins into ZCCCH-type and ZCCHC-type.
• Analysis of the functional diversity and mechanisms of ZNFPs in viral RNA regulation.

Main Results:

• Several host RBPs, particularly zinc finger proteins, play pivotal roles in regulating viral RNA.
• These ZNFPs exhibit dual functions: restricting viral replication or promoting viral persistence.
• ZNFPs can either degrade viral genomes or stabilize them through interactions with cofactors.

Conclusions:

• RNA-binding zinc finger proteins are key regulators of viral RNA, with diverse functional roles.
• Understanding the dual functions of ZNFPs provides insights into viral infection dynamics.
• ZNFPs represent promising therapeutic targets for the development of novel antiviral treatments.
