Information Regarding SWISS-PROT

The SWISS-PROT Protein Knowledgebase is a curated protein sequence database that provides a high level of annotation (such as the description of protein function, domains structure, post-translational modifications, variants, etc.), a minimal level of redundancy and high level of integration with other databases.

A detailed description of a database sequence entry and its format can be found in the User Manual.

Release 40.0 of SWISS-PROT contains 101'602 sequence entries, comprising 37'315'215 amino acids abstracted from 91'880 references. This represents an increase of 18% over release 39.

SWISS-PROT is accompanied by TrEMBL, a computer-annotated supplement to SWISS-PROT. TrEMBL contains the translations of all coding sequences (CDS) present in the DDBJ/EMBL/GenBank Nucleotide Sequence Database and also protein sequences extracted from the literature or submitted to SWISS-PROT, which are not yet integrated into SWISS-PROT.

We would like to encourage laboratories wishing to discuss any collaborations to contact us. For information, comments and/or suggestions, please email us at
