Structure-Based Sequence Alignment of the Transmembrane Domains of All Human GPCRs: Phylogenetic, Structural and Functional Implications
Fig 7
The phylogenetic tree based only on TM similarity using the GRoSS alignment (loops were ignored).
Color coding denotes the GPCR class. Proteins with known crystal structure are emphasized with a dot. The full resolution version of this figure is in S4 Fig.
