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 1 entry per nucleotide submission UniProtKB/Swiss-Prot 1 entry per protein Redundant, automatically annotated - unreviewed Non-redundant, high-quality manual annotation - reviewed

Automatic Annotation for UniProtKB/TrEMBL
UniProtKB/Swiss-Prot manually curated proteins, capturing information available in the literature (~545,000 entries) UniProtKB/Trembl automated annotation only (~56,000,000 entries) Most proteins we now know the sequence of have not been biochemically profiled in any laboratory and probably never will
InterPro - a database which integrates predictive information about proteins' function from partner resources, giving an overview of the families that a protein belongs to and the domains and sites it contains. Users who have novel nucleotide or protein sequences to functionally characterise can use the software package InterProScan to run the scanning algorithms from the InterPro database
Master headline
Automatic Annotation o UniProtKB employs two prediction programs which are referred to as UniRule and SAAS. SAAS, Statistical Automatic Annotation System, generates a new set of decision-trees with every UniProtKB release using datamining. UniRule maintains a set of manually established and maintained annotation rules. Swiss-Prot InterPro

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 wellstudied 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
