Figure 6From: The repertoire of G protein-coupled receptors in the human parasite Schistosoma mansoni and the model organism Schmidtea mediterraneaPhylogenetic analysis of PROF1 GPCRs. Maximum parsimony tree for all identified PROF1 receptors. An alignment block that included TM domains I-IV was bootstrapped 1000 times for parsimony analysis. PROF1 can be subdivided into 3 families with good bootstrap support (> 50%; relevant values displayed): I, II and III. Schistosoma sequences are shown in green and Schmidtea sequences are shown in blue. The tree is rooted with a schistosome opsin-like GPCR (AAF73286.1). Schmidtea PROF1 receptors with transcript expression confirmed by RT-PCR are marked with red asterisks.Back to article page
