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

Area of Science:

• Biochemistry
• Structural Biology
• Bioinformatics

Background:

• Protein information is often fragmented across diverse sources, complicating comparative analysis.
• Simultaneous visualization and comparison of specific protein properties are challenging.
• Understanding protein family conservation and differences requires integrated data.

Purpose of the Study:

• To develop a user-friendly web interface for simultaneous visualization of protein data.
• To integrate multi-sequence protein alignments with 3D structural information.
• To facilitate the comparison of protein properties within families.

Main Methods:

• Development of the ALLIN (Annotation of sequence aLignment and structuraL proteIn visualizatioN) web interface.
• Implementation of features for multi-sequence alignment visualization with comments and annotations.
• Integration of 3D protein structure visualization.
• Inclusion of user-defined coloring schemes for residue annotation.

Main Results:

• ALLIN provides a unified "memo" web page combining data from multiple sources.
• The interface allows flexible highlighting of specific protein properties.
• Users can easily visualize and compare protein alignments and structures without coding expertise.
• The tool facilitates the creation of shareable overviews of protein families.

Conclusions:

• ALLIN simplifies the structure-function analysis of proteins and their variants.
• The tool is particularly beneficial for studying proteins involved in human genetic diseases.
• ALLIN enhances collaborative research by providing easily shareable protein data summaries.
