Essential for the core assembly. Its myristoyl moiety may function as a membrane-anchoring signal to bind the developing core shell to the inner viral envelope. The structural protein p34 is a component of the virus core shell. The structural protein p14 is a component of the virus core shell. The structural protein p37 is a component of the virus core shell. The structural protein p150 is a component of the virus core shell. Found in perinuclear cytoplasmic viral factories during assembly. Found in perinuclear cytoplasmic viral factories during assembly (By similarity). In the virion, located in the core shell, which functions like a matrix between the DNA-containing nucleoid and the inner envelope (By similarity). Found in perinuclear cytoplasmic viral factories during assembly. In the virion, located in the core shell, which functions like a matrix between the DNA-containing nucleoid and the inner envelope. Nuclear at early stages of infection. Found in perinuclear cytoplasmic viral factories during assembly. In the virion, located in the core shell, which functions like a matrix between the DNA-containing nucleoid and the inner envelope. Found in perinuclear cytoplasmic viral factories during assembly. In the virion, located in the core shell, which functions like a matrix between the DNA-containing nucleoid and the inner envelope. Expressed in the late phase of the viral replicative cycle. Specific enzymatic cleavages in vivo by the viral pS273R protease yield mature proteins. Belongs to the asfivirus polyprotein pp220 family.
