Additional file 3. Schematic diagram of Plasmodium knowlesi MSP1 protein domains. Each box in the schematic diagram is representative of the various conserved and variable domains. Domain coordinates have been marked following Putaporntip et al. [39]. Conserved domains I, III, V, VII, and IX are in shaded background whereas variable domains II, IV, VI, and VIII are in dotted background. Signal peptide, trans-membrane domain and Epidermal Growth Factor have been abbreviated as SP, TM and EGF, each respectively.
