About UniProt

Last modified June 22, 2017

The Universal Protein Resource (UniProt) is a comprehensive resource for protein sequence and annotation data. The UniProt databases are the UniProt Knowledgebase (UniProtKB), the UniProt Reference Clusters (UniRef), and the UniProt Archive (UniParc).

UniProt is a collaboration between the European Bioinformatics Institute (EMBL-EBI), the SIB Swiss Institute of Bioinformatics and the Protein Information Resource (PIR). Across the three institutes more than 100 people are involved through different tasks such as database curation, software development and support.

EMBL-EBI and SIB together used to produce Swiss-Prot and TrEMBL, while PIR produced the Protein Sequence Database (PIR-PSD). These two data sets coexisted with different protein sequence coverage and annotation priorities. TrEMBL (Translated EMBL Nucleotide Sequence Data Library) was originally created because sequence data was being generated at a pace that exceeded Swiss-Prot's ability to keep up. Meanwhile, PIR maintained the PIR-PSD and related databases, including iProClass, a database of protein sequences and curated families. In 2002 the three institutes decided to pool their resources and expertise and formed the UniProt consortium.

The UniProt consortium is headed by Alex Bateman (PI), Cathy Wu, and Ioannis Xenarios, supported by key staff, and receives valuable input from an independent Scientific Advisory Board.


UniProt is supported by the National Institutes of Health (NIH), National Human Genome Research Institute (NHGRI) and National Institute of General Medical Sciences (NIGMS) grant U41HG007822. Additional support for the EMBL-EBI's involvement in UniProt comes from European Molecular Biology Laboratory (EMBL), the British Heart Foundation (BHF) (RG/13/5/30112), the Parkinson's Disease United Kingdom (PDUK) GO grant G-1307, and the NIH GO grant U41HG02273. UniProt activities at the SIB are additionally supported by the Swiss Federal Government through the State Secretariat for Education, Research and Innovation SERI. PIR's UniProt activities are also supported by the NIH grants R01GM080646, G08LM010720, and P20GM103446, and the National Science Foundation (NSF) grant DBI-1062520.
