Unlike other retrovirus Gag proteins, the prototype foamy virus (PFV) p71(g)(ag) protein is not processed into mature matrix (MA), capsid (CA), and nucleocapsid (NC) subunits. Little information about sequence motifs involved in FV capsid assembly and release is available. The recent analysis of candidate L-domain motifs in PFV Gag identified an evolutionarily conserved YXXL sequence motif with a potential function in capsid assembly. Here we provide support for the hypothesis that this motif… CONTINUE READING
