Primary (A), secondary (B) and tertiary structures (C) of Schistosoma japonicum tetraspanins (TSPs), SjTSP-2, SjTSP-8, SjTSP-23 and SjTSP-25. In A, B and C blue identifies the SEL domain and red the large extracellular loop (LEL) domain. In B and C green regions show the predicted epitopes and cyan the identified amino acid substitutions. Primary structure was visualised using BioEdit, secondary structure was predicted using PROTTER, and PyMOL molecular visualisation software was used to render the SjTSP tertiary structures
