Fig. 5From: Evolution of tetraspanin antigens in the zoonotic Asian blood fluke Schistosoma japonicumPrincipal component analyses of structural similarity for Schistosoma japonicum tetraspanin (TSP) proteins between provinces for SjTSP-2 (A), SjTSP-8 (B), SjTSP-23 (C) and SjTSP-25 (D). Structural similarity was inferred from z scores produced by the DALI protein comparison server and then plotted using the Tidyverse package [83] in RStudio [84]Back to article page
