In addition, the IgG in 12-months post-infection samples recognized an immunodominant site at the C-terminus of GP2 encompassing the C-terminal heptad repeat (CHR; residues 1950-1967 in complete MARV proteome) and the membrane proximal external region (MPER; residues 1968-1989 in complete MARV proteome). The gene discussed is GP2; the disease is infection.
