Figure 2. Structural domains identified in the S. invicta predicted Vg proteins, (A) Vg1, (B) Vg2, (C) Vg3.

Figure 2

Each protein encoded a putative cleaved signal peptide (black). These proteins possess the LPD-N (gray), DUF1943 (horizontal stripes), and VWD (vertical stripes) domains commonly found in Vg proteins. While Vg2 and Vg3 possessed one of each domain, Vg1 possessed two. Therefore, Vg1 might encode Vg1 and Vg4.
