Fig. 5. Dendrogram of the known leucokinin receptors. A CLUSTAL X protein alignment
was performed using the putative TM spanning regions of the known leucokinin
receptors. From this a phylogram was produced using the TREEVIEW program. TM
domains were predicted using the TMHMM 2.0 program. The scale bar gives an
approximation of the number of substitutions per site. The Lymnaea
stagnalis (pond snail) receptor is used as an outgroup.
