Measles virus attaches with protein H to the surface of cell, once this happens it gives signal to the fusion protein F, which becomes active and initiates virus entry into the cell by membrane fusion. Is there a virus or virus family that acts very similarly however at the end it enters cell not by cell fusion but by endocytosis? The key thing that should be present in virus is the signal transfer from attachment protein to the second protein that would become active and only then would initiate cell entry by endocytosis.
In the case of Vaccinia virus (Poxvirus) first contact and binding to the cell is with GAGs. Then, it's described that it activates endocytosis (fluid phase uptake) signaling by binding to receptors (integrins in this case). Also it's thought that it interacts with other membrane signaling proteins, maybe in a lesser specific way.
I hope it helps you
Often the virus transmitted the cell membrane and attached to the biquitene and then become aminable to proteosome that destruction and present the epitobe
