This is the conserved central domain of the Gag polyprotein from Foamyviruses (FVs) or Spuma-retroviruses. Gag is the major structural protein required for genome packaging virion assembly, trafficking and egress. This domain has an all alpha-helical fold and contains the highly conserved PGQA and YxxLGL sequences [1]. The Gag polyprotein is a core viral polyprotein that undergoes specific enzymatic cleavages in vivo to yield the mature protein. It is involved in capsid formation and genome binding. Shortly after infection, interaction between incoming particle-associated Gag proteins and host dynein allows centrosomal targeting of the viral genome (associated to Gag), prior to nucleus translocation and integration into host genome [2, 3].
