| - | '''Virus coat proteins''' (VCP) or '''capsid proteins''' coat the virus<ref>PMID:14019094</ref>.  The various VCPs are designated as Vp1, Vp2, etc.  The VCP P domain (protruding domain) in noroviruses binds histo blood group antigen receptors.  The outer capsid protein '''VP4''' is a virus spike-forming protein which mediates the virial attachment to the host epithelial cell receptors.  VP4 is an outer capsid protein of non-enveloped viruses. VP4 attaches to sialic acid or to integrin heterodimers<ref>PMID:2538649</ref>.  VP4 domains include: '''VP5*''' which forms the foot of the spike and acts in the permeabilization of the cell membrane and '''VP8*''' which forms the head of the spike and binds to sialic acid. | + | '''Virus coat proteins''' (VCP) or '''capsid proteins''' coat the virus<ref>PMID:14019094</ref>.
