The UniProt consortium European Bioinformatics Institute (EBI), Swiss 
Institute of Bioinformatics (SIB) and Protein Information Resource 
(PIR), is pleased to announce UniProt Release 1.2 (02-Feb-2004). UniProt 
(Universal Protein Resource) is a comprehensive catalog of information 
on proteins.

UniProt Release 1.2 consists of 1,219,569 entries (UniProt/Swiss-Prot: 
143,790 entries and UniProt/TrEMBL: 1,075,779 entries)
UniRef 100 Release 1.2 consists of 1,173,946 entries
UniRef 90 Release 1.2 consists of 712,769 entries
UniRef 50 Release 1.2 consists of 412,299 entries
UniParc Release 1.2 consists of 2,305,130 entries

UniProt databases can be accessed from the web at

UniProt ( is a centralized, authoritative 
resource for protein sequences and functional information with source 
attribution and minimal redundancy. UniProt has been created by joining 
the information contained in Swiss-Prot, TrEMBL, and PIR. UniProt 
provides a fully classified, richly and accurately annotated protein 
sequence knowledgebase, with extensive cross-references and multiple 
query interfaces. For convenient sequence searches, UniProt also 
provides several non-redundant sequence databases.

UniProt is comprised of three components, each optimized for different 
uses. The UniProt Knowledgebase (UniProt) is the central access point 
for extensive curated protein information. The UniProt Non-redundant 
Reference (UniRef) databases combine closely related sequences into a 
single record to speed searches. The UniProt Archive (UniParc) is a 
comprehensive repository, reflecting the history of all protein 
sequences. UniProt is updated bi-weekly and all the databases except 
UniParc can be downloaded from At present UniParc is 
accessible only from the web interface.

UniProt is supported mainly by the National Institutes of Health (NIH) 
grant 1 U01 HG02712-01. Minor support for the EBI’s involvement in 
UniProt comes from the two European Union contracts BioBabel 
(QLRT-2000-00981) and TEMBLOR (QLRI-2001-00015) and from the NIH grant 
1R01HGO2273-01. Swiss-Prot activities at the SIB are supported by the 
Swiss Federal Government through the Federal Office of Education and 
Science. PIR activities are also supported by the National Science 
Foundation (NSF) grants DBI-0138188 and ITR-0205470.
