Overview Direct Submissions Bulk Submissions the SPIN Interface Sequence Release Deposition Metrics Future Developments Gayatri Chavali1 and UniProt Consortium1,2,3 1 EMBL-European Bioinformatics Institute, Cambridge, UK 2SIB Swiss Institute of Bioinformatics, Geneva, Switzerland 3Protein Information Resource, Georgetown University, Washington DC & University of Delaware, USA Sequence Submissions to UniProtKB Overview The SPIN Interface UniProtKB is a comprehensive, centralised resource for protein sequence and functional information. Sequences in UniProtKB are derived primarily from translations of coding sequences submitted to the International Nucleotide Sequence Database Collaboration of ENA, GenBank and DDBJ. Other sources include the wwPDB and gene predictions from Ensembl and RefSeq. Protein sequences are also incorporated into the database as submissions from direct sequencing methods. Direct Submissions UniProt accepts depositions of direct protein/peptide sequences derived from techniques such as Edman degradation and MS/MS. Direct data submissions are accepted from the research community via SPIN, the interactive web-based submission tool. http://www.ebi.ac.uk/swissprot/Submissions/spin/index.jsp In addition to the primary sequence, submitters are asked to provide: • Source Organism • Source strain/tissue • Citation details • Experimental method used to obtain sequence • Any relevant characterisation data SPIN submissions are annotated using data provided by the submitter coupled with results from sequence analysis tools and information propagated from homologous sequences already present in the database. Deposition Metrics Annotation is carried out by maintaining a dialogue with the submitter to ascertain the supporting evidence available for the deposited sequence. A Number of unique 900 sequences unique accession number is assigned to each submitted sequence which 800 Number of unique submitters can be used by the submitter in subsequent publications. 700 600 500 Bulk Submissions 400 300 Sequence submissions occasionally consist of more than 50 sequences. 200 In the event of such situations submitters may provide the sequences in a 100 bulk fasta file.

  • Webnetcoffee
    Hu et al. BMC Bioinformatics (2018) 19:422 https://doi.org/10.1186/s12859-018-2443-4 SOFTWARE Open Access WebNetCoffee: a web-based application to identify functionally conserved proteins from Multiple PPI networks Jialu Hu1,2, Yiqun Gao1, Junhao He1, Yan Zheng1 and Xuequn Shang1* Abstract Background: The discovery of functionally conserved proteins is a tough and important task in system biology. Global network alignment provides a systematic framework to search for these proteins from multiple protein-protein interaction (PPI) networks. Although there exist many web servers for network alignment, no one allows to perform global multiple network alignment tasks on users’ test datasets. Results: Here, we developed a web server WebNetcoffee based on the algorithm of NetCoffee to search for a global network alignment from multiple networks. To build a series of online test datasets, we manually collected 218,339 proteins, 4,009,541 interactions and many other associated protein annotations from several public databases. All these datasets and alignment results are available for download, which can support users to perform algorithm comparison and downstream analyses. Conclusion: WebNetCoffee provides a versatile, interactive and user-friendly interface for easily running alignment tasks on both online datasets and users’ test datasets, managing submitted jobs and visualizing the alignment results through a web browser. Additionally, our web server also facilitates graphical visualization of induced subnetworks for a given protein and its neighborhood. To the best of our knowledge, it is the first web server that facilitates the performing of global alignment for multiple PPI networks. Availability: http://www.nwpu-bioinformatics.com/WebNetCoffee Keywords: Multiple network alignment, Webserver, PPI networks, Protein databases, Gene ontology Background tools [7–10] have been developed to understand molec- Proteins are involved in almost all life processes.

    1 A series of three bases is called a codon which translates into an amino acid. A series of amino acids make a protein. The codon wheel is central to this activity as it translates the DNA sequence into amino acids. To use the wheel you must work from the inside circle out to the outer circle. For example if the first triplet of the sequence is CAT, the amino acid it codes for is Histidine (H). 2 Stress to the students that the amino acid sequence is not the entire amino acid sequence, but a region that we can use to search online databases. Normally, amino acid sequences can be comprised of hundreds of amino acids. By following the link to the Uniprot website at the bottom of the protein profile students will be able to see the full sequence of the protein (if time). 3 4 Before discussing the results, stress to the students that the amino acid sequence is not the entire amino acid sequence, but a region that we can use to search online dbdatabases. Normally, amino acid sequences can be comprised of hundreds of amino acids. By following the link to the Uniprot website at the bottom of the protein profile students will be able to see the full sequence of the protein (if time). The antifreeze protein is essential to prevent organisms like the wolf fish from freezing in icy conditions. Q. Is this just exclusive to this one species / what other species may use antifreeze proteins? Antifreeze proteins are found in other organisms including invertebrates such as the “Snow flea” or springtail, as well as species of plant and some bacteria.
