Molecular Mechanism of Interaction between the Receptor-binding Protein and Fusion Protein during Membrane Fusion Caused by the Paramyxoviruses

The paramyxoviruses mediate membrane fusion between viral envelope and host cell membrane, which leads to entry of the virus into cells. This membrane fusion is caused by an interaction between the attachment protein and fusion protein on the viral envelope. In the study presented here, I carried out chimeric analysis of the fusion proteins of two paramyxiruseses(PIV5 and SV41) and identified the domains that are required for the fusion protein to interact with the attachment protein.
