A modified BLAST, designed to query ortholog group data. It treats each ortholog group as a unit, and instead of providing a ranked list of individual sequence hits, it organizes and ranks the results by ortholog groups, which is often a much more desirable format for functional inference or evolutionary studies.
A simple access point to view gene family assignments, annotations and phylogenetic data for insect immune-related genes and gene families.
miROrtho contains predictions of precursor miRNA genes covering many animal genomes combining evidence from sequence homology and Support Vector Machine classifiers. We provide both consistent extrapolation of already known miRBase families and novel miRNA predictions by our SVM and orthology pipeline.
OMA is a project that aims to identify orthologs among publicly available, complete genomes. With many hundreds of genomes analyzed to date, OMA is one of the largest projects of its kind.
Catalog of eukaryotic orthologous protein-coding genes. OrthoDB explicitly delineates orthologs at each radiation along the species phylogeny. Available protein descriptors, together with Gene Ontology and InterPro attributes, serve to provide general descriptive annotations of the orthologous groups, and facilitate comprehensive database querying. Data sources include proteomes from arthropods, fungi, vertebrates and basal metazoans.
