Figure 3

Alignment of sequences representing the SmGPR clade (cf. Figure 2). Conserved, transmembrane (TM) domains are outlined in red; the most conserved amino acid residues in other sequence regions are in blue, with the least conserved residues in palest. Most sequences within this clade were predicted, using a Support Vector Machine (SVM), to bind to dopamine, with the exception of those with extended N-termini.
