Phylogenetic tree analysis of the TK4 protein in Schistosoma japonicum. All of the following sequences were obtained from the National Center for Biotechnology Information (www.ncbi.nlm.nih.gov): human Frk (NP_002022.1), Hydra Stk (AAA29217.1), human Fgr (NP_005239.1), human Src (P12931.3), Xiphophorus Yes (P27447.3), chicken Yrk (Q02977.2), human Fyn (P06241.3), Xenopus Fyn (CAA36435.1), human Blk (P51451.3), human Lyn (P07948.3), human Hck (P08631.5), monkey Lck (Saimiri sciureus; CAC38871.1), fish Syk (Danio rerio; NP_998008.2), pig Syk (NP_001098422.1), rat Syk (NP_036890.1), mouse Syk (AAA87462.1), human Syk (AAH01645.1), human Zap70 (P43403.1), mouse Zap70 (P43404.3), Schistosoma mansoni TK4 (CAD13249.1), Schistosoma mansoni TK5 (AAF64151.1), Hydra Syk (NP_001296711.1), Schistosoma japonicum TK4 (APD26308.1; indicated by the blue dot). The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The numbers above the branches indicate the bootstrap values in percentages (of 1000 replicates)
