Create a multiple sequence alignment

Build your own multiple sequence alignment

The multiple sequence alignment will be built using the proteins from one or more protein families and a number of protein filters (currently on a species filter is available).

The first step towards having your own multiple sequence alignment built is selecting one or more protein families from the tree. Your are free to select whatever you want, however the quality of the alignment will best if you select families that are close in the tree.
Selected protein families appear on the right side of the page, from where you can remove them if you made a mistake or submit the selected families which will take you to the next step of the process, selecting the filters.

After you have selected you protein families, the filter part is shown. Using these filters you can determine which proteins and wich residue positions are included in the alignment. More information about how the filters work and how to use them is provided when you need it.

Note: Due to computational restrictions it is not possible to generate very large alignments. The upper limit lies around 175,000 residues. This is approximately equivalent to 850 full proteins, or more if you select specific residues to be aligned. If you select a bigger set, you will get a warning telling you that you should limit your selection.

When both the protein families and the filters are submitted, a submit button appears that will submit the alignment job. Please be patient, some jobs can take quite a while.

Select protein families

The GPCRDB family tree

The families in the GPCRDB are organized in a tree-like structure. You can navigate to the family you would like to select by clicking the '+' buttons. You can use the 'Expand' and 'Collapse' links to expand and collapse the tree.

Clicking on the family name selects that protein family. You are free to select as many families as you like, however the quality of the alignment will best if you select families that are close in the tree. Selected protein families appear on the right side of the page, from where you can remove them if you made a mistake or submit the selected families which will take you to the next step.
