Phylogeny-based Protein Function Prediction
SIFTER (Statistical Inference of Function Through Evolutionary Relationships) is a statistical approach to predicting protein function that uses a protein family's phylogenetic tree, as the natural structure for representing protein relationships.
- SIFTER was recently honored as the best-performing sequence-based protein function prediction method in the Critical Assessment of Function Annotation.
- Currently SIFTER has predictions for proteins across species.
- Results are obtained using the family data from Pfam v27.0, the gene ontology data from GO (update 09/2013), and the annotation data from UniProt-GOA (update 09/2013).
- For queries not in our current results, try "Predict by seqence" to find SIFTER predictions for the closest homologs.
