Virus coat protein

Virus coat proteins (VCP) or capsid proteins coat the virus. 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. 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. The biological assembly of HIV-I coat protein is (PDB entry 3gv2). For details on Zika virus capsid protein see Hugo Heringer de Almeida/5YGH.
