UniProtKB comprises two sections: UniProtKB/Swiss-Prot which is manually annotated and is reviewedand UniProtKB/TrEMBL which is automatically annotated and is notreviewed. 2) The UniProt Reference Clusters (UniRef) databases provideclustered sets of sequences from the UniProtKB and selected UniProt Archive records to obtaincomplete coverage of sequence space at several resolutions while hiding redundant sequences. 3) The UniProt Archive (UniParc) is a comprehensive repository， each optimised for different uses: 1) The UniProt Knowledgebase (UniProtKB) is the central accesspoint for extensive curated protein information， classification， including function，used to keep track of sequences and their identifiers. ， highquality and freely accessible resource of protein sequence and functional information. UniProt iscomprised of four components，。
