The entry has only one ortholog in the other species and the orthologous entries have only one ortholog in this species.
How to find 1:1 Orthologs
The entry has more than one ortholog in the other species but all orthologous entries have only one ortholog in this species. This implies that the gene was duplicated in an ancestor of the other species, but after the speciation event.
The entry has only one ortholog in the other species, but the orthologous entry has more than one ortholog in this species. This implies that the gene was duplicated in an ancestor of this species, but after the speciation event.
The entry has more than one ortholog in the other species and the orthologous entries have more than one ortholog in this species. This implies that the gene was duplicated at least twice: in the lineage of the query species and in the lineage of the other species, yet all descend from a common ancestral gene in the last common ancestor of the two species.
We call "close" paralogs the paralogous sequence pairs that are co-orthologous to at least one other entry reported in the list of orthologs. Or in other words, they are in-paralogs with respect to the last common ancestor of all the species represented among the orthologs.
Hierarchical groups contain genes that descend from a single common ancestral gene within a given taxonomic range.
OMA groups contain sets of genes which are all orthologous to one another within group. This implies that there is at most one entry from each species in a group.
OMA Groups functionality
OMA groups contain sets of genes which are all orthologous to one another within the group. This implies that
there is at most one entry from each species in a group.
The fingerprint is a subsequence that is specific to a certain group in the current OMA release.
Since the group number is specific to a release, this is the best way to track a group across
releases.
The numeric OMA Group id is release specific. It is therefor not recommended to use it to track a
group between different releases. Use instead the fingerprint.
Lists all the member proteins of this OMA group in a table.
The protein list can also be exported as unaligned sequences.
Show a Mafft multiple
sequence alignment of the current OMA Group member proteins. Note that this MSA is
computed on the fly. The aligned sequences can be exported in fasta format.
