Last updated on: Mon Apr 16 2012
We have recently adopted a new build procedure that makes use of amino acid sequence searching (blastp) to find more distant relationships, but the procedure still refers to the DNA sequence for computation of some of the statistics. The matching strategy is guided by the taxonomic tree such that more closely related organisms are compared first. Moreover, HomoloGene entries now include paralogs in addition to orthologs.
