Search a comprehensive repository of all protein sequences.
Highlights:
UniParc is the UniProt Archive, the most comprehensive publicly accessible non-redundant protein sequence database available.
New and updated protein sequences are loaded daily from public databases including Swiss-Prot, TrEMBL, PIR-PSD, EMBL, Ensembl, IPI, PDB, RefSeq, FlyBase, WormBase, and European, American, and Japanese Patent Office proteins.
To avoid redundancy, each unique sequence is stored only once and assigned a unique UniParc identifier. These identifiers are stable x97 once created they are never deleted or reassigned.
