Want to learn about a gene function, but there’s no functional data in your species of interest? Or maybe looking for a homologue of your fav gene in a model organism to carry out functional work? Look no further! This #tweetorial will show you how to find orthologues in @ensembl

You can learn more about your #gene by examining phenotypes, diseases and traits associated with #orthologues of this gene in other species listed in the table below, as they might be functionally equivalent. There are numerous phenotypes found in mouse models 🐁

You can explore #sequence alignment of the human and zebrafish orthologues by clicking on the ‘View Sequence Alignments’ link, which gives you an option to view protein or cDNA alignment. Let’s have a look at the protein alignment.

We calculate #ComparativeGenomics analyses by taxa. #EnsemblCompara is dedicated to vertebrates (with a couple of non-vertebrate model organisms 🪰 🪱). You can find similar analysis done for plants 🌱, invertebrate metazoans 🦟, protists 🦠 and fungi 🍄 in @ensemblgenomes

We also calculate genomic comparison across all divisions for a subset of representative species called pan-taxonomic Compara, which can be found in @ensemblgenomes

If you’d like to look at your vertebrate #gene of interest in the pan-taxonomic context, you can get there through a non-vertebrate #orthologue of your gene. Let’s go back to the Orthologue table and search for the Drosophila melanogaster orthologue 🪰

Knowing the Drosophila #orthologue (ScpX), we can search for it in Ensembl Metazoa. You can find the Pan-taxonomic Compara section in the side menu on the #gene tab.

You can also mine #homologues at a larger scale using:
🔹BioMart: ensembl.org/biomart/martvi…
🔹Ensembl REST API: rest.ensembl.org
🔹EMF files on our FTP site: ftp.ensembl.org/pub/release-10…
🔹XML files on our FTP site: ftp.ensembl.org/pub/release-10…
