Evolution of Proteins / Statistics of the Evolutionary Trace

The evolutionary trace method is a systematic, transparent and novel predictive technique that identifies active sites and functional interfaces in proteins with known structre. It is based on the extraction of functionally important residues from sequence conservation and variation patterns in homologous proteins, and on their mapping onto the protein surface to generate clusters identifying functional interfaces. The evolutionary trace has the ability to delineate functional epitopes and identify residues critical to binding specificity. Based on mutational evolutinary analysis and on the structural homology of protein families, this versatile approach should help focus site-directed mutagenesis studies of structure-function relationships in macromolecules, as well as studies of specificity in molecular recognition. More generally, it provides an evolutionary perspective for judging the functional or structural role of each residue in a protein structure.

The evolutionary trace was created by Olivier Lichtarge. Click here to learn more about Dr. Lichtarge and his lab.


Some preliminary statistical analysis has been done on the evolutionary trace procedure as well. The see the thesis proposal written by Heidi Spratt describing the statistical analysis click here.
