As of release 102, we will be removing the gene and protein family analysis from Ensembl. Information on related genes within and between species is still provided by our gene trees, homologues and alignments.

The gene and protein families were calculated using proteins in Ensembl, as well as proteins in UniProt, giving a wider view of gene homology between species. As the number of species in Ensembl greatly increases, we no longer need this extra analysis of homology, as this is covered by the Ensembl gene trees. It also frees up resources to scale up our gene tree analysis for the number of species now going into it.
