uncoating

(noun)

A process in which the viral capsid of a virus is removed, leading to the release of the viral genomic nucleic acid.

Examples of uncoating in the following topics:

  • Antiviral Agents that Prevent Virus Uncoating or Release

    • Another drug target is the uncoating step during viral infection.
    • Uncoating is the process of capsid disintegration, which leads to the release of the genomic material.
    • It is believed that such drugs prevent the virus from uncoating by blocking the proteins on the capsid responsible for uncoating, such as ion channel proteins.
  • Neutralization Reaction

    • It may interfere with virion binding to receptors, block uptake into cells, prevent uncoating of the genomes in endosomes, or cause aggregation of virus particles.
  • Virus Attachment and Genome Entry

    • There are six basic stages in the life cycle of viruses: attachment, penetration, uncoating, replication, assembly of viral particles, and release.
  • Medical Importance of Viruses

    • Once inside a cell, all viruses must uncoat, replicate, and transcribe their genomes, and then repackage their genomes into viral progeny that are released from cells.
  • Viral Replication and Gene Expression

    • Uncoating of the viral RNA is mediated by receptor-dependent destabilization of the virus capsid (2).
  • General Features of Virus Replication

    • Uncoating is a process in which the viral capsid is removed: This may be by degradation by viral or host enzymes or by simple dissociation.
  • Replication of Double-Stranded DNA Viruses of Animals

    • Prior to genome replication, the processes of viral attachment, entry and uncoating occur.
