Polbase(R) is an open repository of DNA polymerase information. The goals are: a) Provide a free and open information resource focused on DNA polymerases; b) Extract primary results from published and unpublished sources; c) Present results in context, without editorial bias, verified by authors; d) Create a polymerase-centric information hub by connecting with other protein resources (PubMed, PDB, UniProt, etc.); e) Be responsive to community suggestions; f) Remain current by automatically identifying newly published papers; g) Sustainability! By engaging the polymerase research community we can produce a valuable resource with minimal effort from any individual contributor The DNA Polymerase Database (Polbase) is intended to compile the wealth of existing DNA Polymerase information from public and private records into an open, searchable database. It supplements existing resources: a) PubMed; b) ExPASy; c) UniProtKB; d) RCSB PDB; e) KEGG; f) PROSITE; g) BRENDA; h) Human Polymerase Gamma Mutation Database. ... [Information of the supplier]

The membrane organization and subcellular location of a protein can provide information about its functional role. Historically, these data have been difficult to produce on a large scale for higher eukaryotic organisms. However, recent advances in membrane organization prediction methods and high-throughput subcellular localization assays have made it possible to generate these datasets. LOCATE is a curated, web-accessible database that houses data describing the membrane organization and subcellular localization of proteins from the FANTOM3 Isoform Protein Sequence set. Membrane organization is predicted by the high-throughput, computational pipeline MemO. The subcellular locations of selected proteins from this set were determined by a high-throughput, immunofluorescence-based assay and by manually reviewing over 1700 peer-reviewed publications. The results of the MemO pipeline and the subcellular localization methods are stored in the database with supporting information including a graphical depiction of the membrane organization juxtaposed with InterPro-predicted features and links to several external databases. The database is searchable by subcellular location, protein class, descriptive keyword, and sequence similarity. The data are retrievable in human- and machine-readable formats and in batch. ...

The Membrane Protein Data Bank (MPDB) is an online, searchable, relational database of structural and functional information on integral, anchored and peripheral membrane proteins and peptides. Data originates from the Protein Data Bank and other databases, and from the literature. Structures are based on X-ray and electron diffraction, nuclear magnetic resonance and cryoelectron microscopy. The MPDB is searchable online by protein characteristic, structure determination method, crystallization technique, detergent, temperature, pH, author, etc. Record entries are hyperlinked to the PDB and Pfam for viewing sequence, three-dimensional structure and domain architecture, and for downloading coordinates. Links to PubMed are also provided. ... [Information of the supplier]
Organs and organelles represent core biological systems in mammals, but the diversity in protein composition remains unclear. Here, we combine subcellular fractionation with exhaustive tandem mass spectrometry-based shotgun sequencing to examine the protein content of four major organellar compartments (cytosol, membranes [microsomes], mitochondria and nuclei) in six organs (brain, heart, kidney, liver, lung and placenta) of the laboratory mouse, Mus musculus. Using rigorous statistical filtering and machine-learning methods, the subcellular localization of 3274 of the 4768 proteins identified was determined with high-confidence, including 1503 previously uncharacterized factors, while tissue-selectivity was evaluated by comparison to previously reported mRNA expression patterns. This molecular compendium, fully accessible via a searchable web-browser interface, serves as a reliable reference of the expressed tissue and organelle proteomes of a leading model mammal. ...

Organelle DB compiles protein localization data from organisms spanning the eukaryotic kingdom and presents an organized catalog of the known protein constituents of more than 50 organelles, subcellular structures, and protein complexes. The data sets in Organelle DB encompass 138 organisms with emphasis on the major model systems: S. cerevisiae, A. thaliana, D. melanogaster, C. elegans, M. musculus, and human proteins as well. In particular, Organelle DB is a central repository of yeast protein localization data, incorporating results from both previous and current (ongoing) large-scale studies of protein localization in Saccharomyces cerevisiae. In addition, we have manually curated several recent subcellular proteomic studies for incorporation in Organelle DB. In total, Organelle DB is a singular resource consolidating our knowledge of the protein composition of eukaryotic organelles and subcellular structures. ... [Information of the supplier]
PenBase provides comprehensive information about penaeidin properties, function, diversity and nomenclature. PenBase contains a Database section that lists all known penaeidins by subgroup or shrimp species. (...) Antimicrobial peptides are major components of innate immunity that have been conserved in evolution and found in different phyla of the plant and animal kingdom. Antimicrobial peptides are often small cationic molecules widely distributed in the whole living kingdom where they participate to host defence reactions against invading microorganisms. They are known to be involved in the innate immune response of vertebrate, invertebrate and plant species, and they are thought to be essential in organisms which lack adaptive immunity. Penaeidins are members of a family of antimicrobial peptides, originally isolated from the shrimp Litopenaeus vannamei, which present both Gram-positive antibacterial and antifungal activities (Destoumieux et al, 1997). Penaeidins appear to be a family of antimicrobial peptides ubiquitous among penaeid shrimps where they are major actors of the immune response (Bachère et al., 2004). ...

PROSITE is a database of protein families and domains. It consists of biologically significant sites, patterns and profiles that help to reliably identify to which known protein family (if any) a new sequence belongs. [Information of the supplier]
Proteomik ist eine sehr junge Forschungsrichtung mit einer sehr viel älteren Wurzel: der Proteinanalytik. Diese befaßt sich mit der Aufklärung von molekularen Eigenschaften wie Aminosäuresequenz, dreidimensionale Struktur und biologische Aktivität individueller Proteine. Untersuchungsgegenstand der Proteomik ist demgegenüber die Gesamtheit aller Proteine in einer biologischen Probe im Moment der Untersuchung und bei den dafür gültigen Bedingungen. Dafür wurde vor etwa 7 Jahren der Begriff "Proteom" geprägt. Die DGPF versteht sich als Plattform, um die in Deutschland an verschiedenen Standorten und im Rahmen unterschiedlicher Programme angelaufenen Proteomik-Aktivitäten unter einem Dach zusammenzuführen und darüber hinaus die Proteomforschung durch national und international abgestimmte Initiativen voranzubringen. Durch eine übergreifende Koordination soll eine Bündelung und optimale Nutzung der nationalen Forschungs-kapazitäten herbeigeführt werden, um im weltweiten Wettbewerb an führender Stelle bestehen zu können. ...
