Protein co-evolution: how do we combine bioinformatics and experimental approaches?

Area of Science:

• Biochemistry
• Bioinformatics
• Molecular Biology

Background:

• Molecular co-evolution involves compensatory protein changes for environmental adaptation.
• Bioinformatics methods detect co-evolution at protein or residue levels, aiding in predicting interactions and functions.
• Understanding functional implications of co-evolutionary sequence divergence remains a challenge.

Purpose of the Study:

• To review recent advances in both bioinformatics and experimental approaches to studying protein co-evolution.
• To discuss the synergy between computational and experimental methods for identifying co-evolutionary signals.
• To elucidate the impact of co-evolution on protein structure and function.

Main Methods:

• Review of current bioinformatics techniques for detecting protein co-evolutionary signals.
• Examination of experimental methodologies used to study individual protein co-evolution.
• Discussion of integrated approaches combining computational and experimental data.

Main Results:
