Trait-to-Gene A Computational Method for Predicting the Function of Uncharacterized Genes

The function of unknown genes is often inferred from comparisons to well-characterized homologs. In this paper, we show that, even if all of the homologs of a gene are unannotated, its function may be deduced through phylogenetic profiling. We have designed a series of algorithms that make functional predictions of genes based on orthology and set theory, but our approach to predicting gene function requires no previous knowledge of homolog …
