Welcome. ParalogyDB is database of paralogy relation between genes, inside a genome (intra-genome paralogy) and between genomes (inter-genome paralogy). Visit our tutorial and glossary to know more about paralogy, paralogyDB and what we have for you in paralogyDB and how to better use paralogyDB.

Go to database in brief Note: Currently we are serving only eukaryotic protein-coding genes intra-genome paralogy, but we are continuously working to broaden the database. To give you an overview of the database content, we prepared the database in brief page which shows a table of species currently included in database, their paralogy statistics and relevant links.
Featured organisms:
Classify your genes and sequences

Classify one or all of genes and sequences retrived from any desired species using one of paralogy classifiers methods of paralogyDB.

Draw networks

Search for a gene ID or Domain ID and draw a network of gene-gene paralogy relation or a network of gene-domain relation and download your network.
