Figure 3.

Alignment of the 7TM region of selected family-B GPCRs. The alignment was generated using the Multiple Alignment General Interface (MAGI) suite of software (alignment using ClustalW [49], display of results using Boxshade) at the UK Human Genome Mapping Project Resource Centre [37]. Black background indicates conserved residues; gray background indicates similar residues; TM1-TM7 indicate transmembrane domains. See text and Table 1 for abbreviations.
