Schematic diagram of (A) the Duffy binding protein and (B) the merozoite surface protein-1. The black regions indicate the targeted sites of domain II (pvdbpII) and the 42-kDa region (pvmsp142) selected for amplicon sequencing, with numbers indicating the amino acid boundaries. Shown are the crystal structure of the pvdbpII dimer (PDB ID: 3RRC)15 and the predicted structure of pvmsp142 (AlphaFold ID: F1AQZ6). The target amplicons contain a 395-bp variable region of pvdbpII and a 341-bp variable region of pvmsp142, respectively.
