Since 2002 a merger and collaboration of three databases: Swiss-Prot & TrEMBL PIR-PSD Funded mainly by NIH (US) to be the highest quality, most thoroughly annotated protein sequence database o A high quality protein sequence database A non redundant protein database, with maximal coverage including splice isoforms, disease variant and PTMs. Sequence archiving essential. o Easy protein identification Stable identifiers and consistent nomenclature/controlled vocabularies o Thorough protein annotation Detailed information on protein function, biological processes, molecular interactions and pathways cross-referenced to external source UniProtKB/TrEMBL UniProtKB/Swiss-Prot 1 entry per nucleotide submission 1 entry per protein Redundant, automatically Non-redundant, high-quality manual annotated - unreviewed annotation - reviewed UniProt/TrEMBL Sub/ ENA (EMBL) DNA database PDB Peptide Ensembl Data VEGA mRNA Patent FlyBase WormBase (Sanger) Data Data 6 02.06.2014 Manual annotation of UniProtKB/Swiss-Prot Splice variants Sequence Sequence features UniProtKB Ontologies Annotations Nomenclature References www.uniprot.org Beta.uniprot.org Sequence curation, stable identifiers, versioning and archiving For example – erroneous gene model predictions, frameshifts…. ..premature stop codons, read-throughs, erroneous initiator methionines…..

SAAS, Statistical UniRule maintains a Automatic Annotation set of manually System, generates a established and new set of decision-trees maintained annotation with every UniProtKB rules. release using data- mining. Swiss-Prot InterPro Master headline Proteomes Definition: The complete proteome of an organism is all the proteins expressed by that organism Two types of Proteomes Complete proteomes Complete sets of proteins thought to be expressed by organisms whose genomes have been completely sequenced. Reference proteomes Some complete proteomes have been selected as reference proteome sets. These cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical research. Requirements for Complete Proteomes • Completely sequenced genome • Good gene prediction models • Proteins are mapped to genome • Good quality transcriptome/proteome data Obtaining Proteomes • Stuck?
