Mutational analysis of heptad repeats in the membrane-proximal region of Newcastle disease virus HN protein.


For most paramyxoviruses, syncytium formation requires the expression of both surface glycoproteins (HN and F) in the same cell, and evidence suggests that fusion involves a specific interaction between the HN and F proteins (X. Hu et al., J. Virol. 66:1528-1534, 1992). The stalk region of the Newcastle disease virus (NDV) HN protein has been implicated in… (More)
