ALLIN: A tool for annotation of a protein alignment combined with structural visualization

Le résumé fourni par la source

The physiological, functional, and structural properties of proteins and their pathogenic variants can be summarized using many tools. The information relating to a single protein is often spread among different sources requiring different programs for access. It is not always easy to select, simultaneously visualize, and compare specific properties of different proteins. On the other hand, comparing members of the same protein family could suggest conserved properties or highlight significant differences. We have thus developed a web interface, ALLIN (Annotation of sequence aLignment and structuraL proteIn visualizatioN) for the simultaneous visualization of multi-sequence protein alignments, including comments and annotations, and the related three-dimensional structures. This interface permits the inclusion of comments and coloring of residues in the alignment section, according to a user-defined color code, allowing a quick overview of specific properties. The interface does not require training or coding expertise, and the result is a unique "memo" web page that combines data from different sources, with the flexibility to highlight only the information of interest. The output provides an overview of the state of art of a protein family that is easily shared among researchers and new data can be conveniently added as it emerges. We believe the ALLIN tool can be useful for all scientists working on the structure-function analysis of proteins, in particular on those involved in human genetic diseases.
