Comments Information

    • Mechanism

    • Peptides derived from the HRC of paramyxovirus F proteins interfere with formation of the six-helix bundle in a dominant-negative manner by binding to the transiently exposed HRN coiled coil in the transient fusion intermediate, thereby inhibiting membrane fusion.

Literature Information

  • ·Literature 1

    • Title

    • Broad spectrum antiviral activity for paramyxoviruses is modulated by biophysical properties of fusion inhibitory peptides
