'*' indicates organisms where new genome annotation data is used in this build.
Last updated on: Mon Jul 28 2008
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.
Sources of Additional Information
HomoloGene entries have been augumented with homology and phenotype information drawn from the following sources.
Online Mendelian Inheritance in Man (OMIM)
Mouse Genome Informatics (MGI)
Zebrafish Information Network (ZFIN)
Saccharomyces Genome Database (SGD)
Clusters of Orthologous Groups (COG)
FlyBase
