Introduction Sequence Feature Variant Type (SFVT) Host-virus Interaction Data • The Virus Pathogen Database and Analysis Resource (ViPR, www.viprbrc.org), sponsored by the National Institute of Allergy and Infectious Diseases serves as a single publicly-accessible repository of integrated datasets and analysis tools for 14 different virus families to support wet-bench virology researchers focusing on the development of diagnostics, prophylactics, vaccines, and treatments for these pathogens1. • ViPRSupports 14 Virus Families • Arenaviridae, Bunyaviridae, Caliciviridae, Coronaviridae, Filoviridae, Flaviviridae, Hepeviridae, Herpesviridae, Paramyxoviridae, Picornaviridae, Poxviridae, Reoviridae, Rhabdoviridae, and Togaviridae. • ViPRIntergrates Data from Many Sources • GenBank sequence records, gene annotations, and strain metadata • Gene Ontology (GO) classifications • UniProtKBprotein annotations • Protein Databank (PDB) 3D protein structures • Immune epitopes from the Immune Epitope Database (IEDB) • Clinical data • Host-Pathogen Interaction Data generated from the NIAID Systems Virology projects and the ViPR-funded Driving Biological Projects • Additional data derived from computational algorithms • ViPR Provides Analysis and Visualization Tools • Genome Annotator • BLAST Sequence Similarity Search • Multiple Sequence Alignment • Phylogenetic Tree Construction • 3D Protein Structures with Sequence Feature or Epitope Highlights • Sequence Feature Variant Type (SFVT) Analysis • Metadata-driven Comparative Genomics Analysis • SNP Analysis • ViPR enables you to store and share data and results through the ViPR Workbench • Sequence Features (SFs): characterized structural, functional, immune epitope, or sequence alteration regions of a protein manually curated from UniProt2, GenBank3, and the Immune Epitope Database4and then validated by expert researchers. • Variant Type (VT): Polymorphisms in each Sequence Feature are identified as “Variant Types” of the Sequence Feature. • Available for hepatitis C virus subtype 1a, Dengue virus type 1-4, and Orthopoxvirus (Vaccinia) in ViPR. • Enables researchers to quickly query and analyze the genotypic changes for all sequence records that could be associated with a given phenotype.

Multiple Sequence Alignment, Phylogenetic Tree and Metadata-driven Comparative Analysis Tool Summary • ViPRcombines the strength of a relational database with a suite of bioinformaticsintegrated tools to support everything from basic sequence and structural analyses to genotype-phenotype studies and host-virus interaction studies. The uniqueness of ViPR lies in: • integrating data from various sources • capturing unique data on hostresponses to virus infections • encouraging the analysis of the comprehensive data contained within the system • combining the available tools to quickly perform complex analytical workflows • facilitating rapid hypothesis generation using bioinformatics methods for subsequent experimental testing • allowing data sharing and storage with collaborators A B C Acknowledgements We would like to thank the primary data providers for the data that was used throughout this study. We also recognize the scientific and technical personnel responsible for supporting and developing ViPR, which has been wholly supported with federal funds from the NIH/NIAID (N01AI2008038 to R.H.S.).
