pfam03276: Gag_spuma_N (This model is not part of the current CDD release)
Spumavirus gag protein, N-terminal
This is the conserved N-terminal 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 region corresponds to the Env-binding domain containing the cytoplasmic targeting and retention sequence (CTRS).
